AB  - Toxic elements, lead, and copper are often found in wastewater discharged from industries such as mining. The discharge of untreated effluent poses severe environmental challenges and sorption methods using agricultural waste materials are proposed as an efficient and cost-effective solution. For this research, activated sunflower material (ASM) was prepared from abundantly available agricultural sunflower waste residues and utilised to remove Pb2+ and Cu2+ ions from an aqueous medium. To begin, we examine variables that may have an impact on the adsorption process, such as pH, contact time, adsorbent dose, and initial concentration using Box-Behnken Design (BBD) to find optimal conditions. Maximum removal efficiency was found at a pH of 5, contact time of 180 min, and initial concentration of 50 mg/L for Pb2+ and 150 mg/L for Cu2+. Additionally, adsorbent dose differed by element, for Cu2+ it was 200 mg, whilst for Pb2+ it was 124 mg. Features of activated carbon such as morphology, elemental composition, textural properties, and surface functionalities were characterised using SEM-EDS, BET, FTIR, and XPS. The adsorption equilibrium data were analysed by Langmuir, Freundlich, and Dubinin-Radushkevich isotherm models. It was found that the obtained results for Pb2+ adsorption were better described with the Freundlich isotherm model. Maximum adsorption capacities for Pb2+ and Cu2+ were 91.8 mg/g and 20.5 mg/g, respectively. Furthermore, kinetic studies confirmed that the adsorption process followed a pseudo-first-order kinetic model for Pb2+, but for Cu2+ all applied kinetic models fitted experimental data with the same values of the correlation coefficient (R2 = 0.99). After comprehensive analysis using the methods mentioned above, ASM was tested for the removal of Cu2+ from mining wastewater sample, and the obtained removal efficiency was 98.6% ± 2.0%. The results of desorption experiments conducted, confirm that ASM has good potential to be reused for the purpose of removing Cu2+ from wastewater.

AB  - The purpose of this study is to evaluate the feasibility of using the originally developed Laser Induced Breakdown Spectroscopy (LIBS) laboratory setup for the qualitative analysis of human tooth tissues and tooth restorations. Plasma was induced by the infrared TEA (Transversally Excited Atmospheric) CO2 laser in the air under atmospheric pressure. Optical emission spectra with sharp and well-resolved spectral lines and a negligibly low background were obtained. The results of the qualitative analysis showed the presence of various elements in the tooth tissues (P, Ca, and Mg), as well as trace elements within restorations such as Zn, Sn, Cu, Ag, and Hg. The estimated temperatures of plasma for composite, dentin, and amalgam were 21,000 K, 16,200 K, and 13,300 K respectively. The electron density deduced from the Stark-broadening line profiles varies from 8.5 × 1017 cm− 3 for amalgam, 2 × 1018 cm− 3 for composite, and 1.9 × 1018 cm− 3 for dentin. The surface of the tooth tissue was imaged with a scanning electron microscope (SEM), showing that dentin contains pores, cavities and bubbles. The results indicated that the alternative and cost-effective LIBS system can be used as a useful tool for further research on laser-induced plasma in dentistry. These insights are useful in the field of laser dentistry, where lasers are commonly utilized to treat teeth. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Different industrial processes can potentially discharge heavy metals into surface and underground waters. These heavy metals can subsequently accumulate in organisms, posing a significant risk to both the environment and human health. Carbon-based materials such as biochar, carbon nanotubes-based materials, and activated carbon have been extensively researched for their effectiveness in adsorbing heavy metals from aqueous solutions [1]. Today, there is an increased interest in the usage of different low-cost, abundantly available lignocellulosic waste as a precursor for the production of activated carbon material. Activated carbon materials produced from different types of agricultural waste are widely used as adsorbent material for the removal of organic and inorganic pollutants from wastewater. High adsorption capacity is associated with characteristics of the adsorbent such as a large specific surface area, pore structure development, and the presence of different types of functional groups [2]. In this work, activated carbon is produced by the carbonization of sunflower agricultural waste followed by an activation process with potassium hydroxide. Activated carbon samples were characterized by SEM-EDS, BET, FTIR, and XPS. The obtained material has a porous structure with micropores and a large specific surface area, exhibiting a high affinity for the adsorption of lead and copper. Additionally, the main mechanism of lead and copper adsorption by sunflower-derived activated carbon has been successfully predicted.

AB  - The industrial wastewater produced from various industries contains a significant amount of pollutants among which are heavy metals and represents one of the leading environmental problems facing public health. Conventional wastewater treatment technologies unsuccessfully remove heavy metals completely. As an alternative to various conventional treatment technologies such as ion exchange, chemical precipitation, and electrochemical treatment which have a lot of drawbacks, biosorption is a process characterized by the use of low-cost and abundant agricultural materials with no significant costs and high sorption potentials of biosorbent due to the presence of carboxylic and phenolic groups in lignocellulose matrix. In Serbia, sunflower is the most common oil plant and grows on about 180 000 ha. After industrial processing between 325, 000 and 360, 000 t of sunflower waste ends up in landfills or is used as a source of energy (1). In this work, the sunflower husk was used to remove Ni from aqueous solutions and wastewater sample. The sunflower husk treated with 1% hydrochloric acid was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). In addition, under optimal conditions, the concentration of Ni in wastewater samplewas obtained and compared by two techniques, induced coupled plasma optical emission spectrometry (ICP-OES) as a standard reference method and laser-induced plasma spectroscopy (LIBS) as a non-standard analytical method. The results of these two methods were compared, to investigate the possibility of using laser-induced plasma spectroscopy as a green alternative for the evaluation of biosorption efficiency.

In this work, the sunflower husk was used to remove Ni from aqueous solutions and wastewater sample. The sunflower husk treated with 1% hydrochloric acid was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). In addition, under optimal conditions, the concentration of Ni in wastewater samplewas obtained and compared by two techniques, induced coupled plasma optical emission spectrometry (ICP-OES) as a standard reference method and laser-induced plasma spectroscopy (LIBS) as a non-standard analytical method. The results of these two methods were compared, to investigate the possibility of using laser-induced plasma spectroscopy as a green alternative for the evaluation of biosorption efficiency.",

AB  - Nanoparticle (NP) signal enhancement is a novel, intensively studied and applied methodology in laser-induced breakdown spectroscopy (NELIBS) [1,2]. In the present study, we tested the effect of the duration, intensity-time profile and wavelength of the laser pulses on the performance of NELIBS analysis of solid samples. Three different laser sources (a transversely excited atmospheric CO2 laser, a fiber laser and a Nd:YAG laser) with three wavelengths (266 nm, 1064 nm and 10.6 µm) and controllable waveforms were used in the experiments, in which we studied the signal enhancement factor and the time evolution of plasma characteristics. Different size silver, gold and binary NPs were prepared for the experiments using chemical and physical particle generation methodologies and applied to the samples using the droplet deposition method. The NELIBS signal enhancement was studied for several trace elements in steel, aluminum and plastic samples.

AB  - In the past two decades, with recent advances in laser technology, Laser-Induced Breakdown Spectroscopy (LIBS) has become a more and more popular analytical method for the analysis of any type of samples. Some exclusive properties such as rapid, multi-element analysis of any kind of material, non-contact and almost non-destructive, independent of sample conductivity, geometry and size make this method superior to the other standard optical emission techniques. In this work, we will demonstrate the possibility of using a cost-effective alternative to commercial LIBS systems, the TEA CO2 laser-based LIBS setup for analysis of environmental-related samples: for direct analysis of solid samples and indirect analysis of liquid samples. Finally, our developed method doesn’t use any hazardous reagents and solvents and maximizes safety for operators and the environment, which creates it in full accordance with the principles of green analytical chemistry.

AB  - Presented research aimed to develop an alternative approach for the estimation of biosorption capability of sunflower husk. The acid-pretreated sunflower biomass was characterized by scanning electron microscopy combined with energy dispersive X-Ray spectroscopy (SEM-EDX) analysis and Fourier transform infrared (FTIR) spectroscopy. Biosorption efficiency has been evaluated using inductively coupled plasma optical emission spectroscopy (ICP-OES) and laser-induced breakdown spectroscopy (LIBS). The adsorption capacity of the adsorbent was determined as the function of the pH of the solution, the initial concentration of heavy metal solutions, and contact time. The optimal conditions were achieved after 15 min of contact at pH 6, while the percentage of the removal was from 80.0–98.7 %, depending on the element. The results obtained from the kinetic and isotherm studies show that maximum adsorption of ions was quickly reached and followed the pseudo-second-order kinetic model. Real samples were tested and obtained Ni values by LIBS method were 3100±200 and 1240±100 mg kg-1, while estimated values by the ICP-OES were 2995±20 and 1130±10 mg kg-1, respectively. The obtained results prove that LIBS method can be used as a “green alternative” for the evaluation of biosorption efficiency.

AB  - Gallic acid (GA) is one of the most important and present natural phenolic compounds due to its well-known biological properties, and its detection and monitoring is of great importance. Silver nanoparticles (AgNPs) are one of the most studied metallic nanomaterials used in various fields, from biomedical applications to electrochemical sensing devices. In this work, we used the pulsed laser ablation technique in liquid for the one-step preparation of nanoparticles of silver from a pure silver plate base in N,N-dimethylformamide. Obtained nanomaterial was characterized using morphological and electrochemical methods and used for modification of screen-printed carbon electrodes (SPCE). Successful immobilization at the surface is confirmed using the surface profiling method. A newly obtained sensor was used for the detection of GA. After parameters optimization, a differential pulse voltammetric protocol was developed, using two approaches - concentration vs. current (GA determination) and peak area vs. current (estimation of the antioxidant capacity). For the first approach sensor linearity was found to be in the range from 0.50 µM to 10 µM, with the limit of detection (LOD) of 0.16 µM and limit of quantification (LOQ) of 0.50 µM. In the second system operating linear range was the same, while LOD and LOQ were 0.11 µM and 0.34 µM, respectively. Practical application of the method was tested using two approaches: direct measurement of gallic acid in biological fluids and estimation of the antioxidant capacity and food quality purpose.

AB  - X-ray Fluorescence (XRF) is the most commonly used non-destructive method offering the user a portable handheld analyzer that delivers fast, accurate results. On the other hand, in the past two decades, with recent advances in laser technology,laser-induced breakdown spectroscopy (LIBS) becomes a more and more popular analytical method for the analysis of solid samples. The ability to provide a fast and multielement analytical response directly from a solid sample makes both LIBS and XRF very versatile tools for soil analysis [1]. Both methods have their advantages, however, in certain circumstances, one is better to use over the other. This paper focuses on the analytical capability of both methods for soil quality management. The main LIBS advantage against XRF is that it can be used for detection of all elements of the Periodic Table, including light elements (C, N, O, S) important for estimation of soil quality [2]. For this paper, 2 samples of soil were used. A real sample was collected in the INS Vinča and certified reference material Metals in Soil obtained from Sigma Aldrich were used for these experiments. A real soil sample was dried at 70℃, homogenized, and sieved using a 100 mesh sieve. Single element calibration standards of Cu, Hg, Ni, Pb, and Cd from J.T. Baker were used for standard addition samples preparation [3]. To homogenized sample portions of fixed mass (5 g) varying amounts of certified standard analyte solutions are added, and the mixture is diluted with 20 ml deionized water. Mixtures were homogenized and dried at 70℃ overnight. The obtained powdered materials were used for the preparation of pressed pellets, including the CRM sample. All samples were analyzed by a unique TEA CO2 based LIBS setup developed in INS Vinča and commercially available Niton XL3 handheld XRF analyzer, Thermo Fischer Scientific. The precision and accuracy of the LIBS method were evaluated and compared to those obtained by XRF. The preliminary results showed that limits of detection for most of the investigated elements are comparable or better than those obtained with XRF.

AB  - With the growth of the industrial world and the rise of anthropogenic activities, environmental challenges have also increased. Wastewater, especially from industrial sources can contain a wide variety of heavy metals [1]. The presence of heavy metals in water resources is a cause for concern due to their toxicity and tendency to bioaccumulation, which leads to significant problems for the environment as well as for animals and humans [2]. There are various conventional treatment technologies that are used for the removal of heavy metals from wastewater such as reverse osmosis, electrodialysis, ultrafiltration, industrial ion exchange process, and chemical precipitation. These techniques have some drawbacks such a being expensive due to high reagent and energy requirements, incomplete metal removal at low concentrations of heavy metals and generation of sludge [1]. Therefore, biosorption has been the subject of research by scientists for almost 70 years in order to find efficient, effective, and low-cost biomaterials for wastewater treatment [3]. In this study, a sunflower husk treated with 1% hydrochloric acid was used to evaluate removal efficiency for Ni from real wastewater samples, as well as to estimate the adsorption capacity as a function of contact time between the heavy metal ions such as Cd in the aqueous solution and the sunflower husk as a biosorbent. Two techniques were used for quantitative analysis, Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) as a standard reference method and laser-induced plasma spectroscopy (LIBS) as an innovative non-standard analytical method. What makes the LIBS superior from the other standard optical techniques is that it allows fast multi-elemental analysis without prior sample preparation, leads to minimal sample damage, and is considered almost non-destructive, this method is also by the principles of green analytical chemistry, which means that it does not use toxic reagents and therefore no chemical waste [4]. The results of these two methods were compared, to examine the possibility of using laser-induced plasma spectroscopy as an alternative green analytical technology for quantitative analysis of sunflower husk as a biosorbent and evaluation of biosorption efficiency as a function of contact time.
