AB  - Due to extensive food production, organophosphate pesticides (OPs) are widely utilized for crop protection, leading to their presence in the environment. The focus of this study was the design of an efficient aqueous biphasic system (ABS) strategy for OP removal, namely, malathion (MAL), azinphos-methyl (AZM), and chlorpyrifos (CHP) from water. Different ionic liquids (ILs) with symmetrical cations were selected as ABS phase- formers (tetrabutylphosphonium salicylate, tetrabutylammonium salicylate, 1,3-dibutylimidazolium dicyanamide, 1,3-dibutylimidazolium salicylate and 1,3-dibutylimidazolium bromide) with citrate salt as a salting-out agent. Initially, phase diagrams were determined, followed by partition studies revealing that the partition of MAL and CHP aligns with the IL- ABS formation trend, while the AZM partition is governed by specific interactions with ILs. For optimization studies, tetrabutylphosphonium-salicylate i.e. [TBP][Sal]-based ABS was chosen, due to obtained high extraction efficiencies of over 99.3 %. After establishing the effects of pH, temperature, tie-line length, and phase ratio on extraction performance, extraction of OPs from a real wastewater sample further confirmed the effectiveness of the designed method achieving complete removal of each pesticide. Furthermore, recovery of IL was achieved using an antisolvent method to precipitate CHP followed by IL-reuse in three consecutive cycles without efficiency decreased. Finally, it was demonstrated that [TBP][Sal] exhibits low cytotoxic potential, indicating that the presence of low amounts of this IL in aqueous media could be acceptable from ecotoxicological standpoint. This study showcased the exceptional potential of the proposed technology for the efficient and sustainable treatment of wastewater contaminated with OPs, affirming its capability to treat significant wastewater volumes.

AB  - The consistent expansion of the lithium-ion battery (LIB) market, coupled with their relatively brief lifespan, necessitates the development of efficient and sustainable LIB recycling strategies. Recycling is crucial not only for the recovery of critical metals like Co(II) and Li(I) from the cathode material as a secondary resource but also from an environmental perspective. This study explores the use of a series of aqueous biphasic systems (ABS) with synthesized tetrabutylphosphonium ionic liquids (ILs) and ammonium sulfate as extraction platforms for metals from LIB cathode. Firstly, liquid–liquid equilibrium phase diagrams for each ABS were established, and partitioning experiments were conducted to assess the Co(II), Ni(II), Mn(II), and Li(I) recovery efficiencies. We observed distinct partitioning behaviors for the metals, with tetrabutylphosphonium diethylenetriaminepentaacetate, [TBP][DTPA], showing recovery efficiencies exceeding 98% for Co(II), Ni(II), and Mn(II). At the same time, Li(I) was predominantly retained in the aqueous salt-rich phase. By fine-tuning ABS operational parameters such as pH, temperature, system composition, and phase ratio, we identified optimal conditions for extracting metals from the cathode material of lithium-cobalt-oxide (LCO) batteries using sulfate lixiviate. Introducing [TBP][DTPA] after the leaching process induced ABS, achieving remarkable recovery efficiency over 95% for Co(II) in the IL-rich phase, with all Li(I) remaining in the lower phase. Cobalt was subsequently extracted using oxalic acid to precipitate as Co-oxalate from concentrate, while Li(I) was isolated from the aqueous phase using ammonium carbonate. After the “cleaning” of the IL-rich phase, the [TBP][DTPA] was recovered and reused in four consecutive cycles, with small detected losses on the recovery efficiency of Co(II) and Li(I). Therefore, our innovative strategy combines sulfate-based lixiviants with IL-ABS technology, thereby enhancing selectivity and sustainability within one of the most efficient lixiviant systems widely employed in the industry. This technological advancement presents a promising pathway for the recycling of spent batteries, offering substantial environmental advantages within the well-established and extensively utilized realm of metal recovery technology in the industry.

AB  - This study explores the use of a series of cholinium ionic liquids (ILs) or salts in combination with polypropylene glycol 400 to form aqueous biphasic systems (ABS) for extracting various polarity pesticides (dicamba, clomazone, pyraclostrobin, and deltamethrin) from water. We assessed five cholinium-based salting-out agents ([Ch][DHP], [Ch]Cl, [Ch][Ac], [Ch][Lac], and [Ch][Nic]), chosen for their structural diversity and unique properties, such as high salting-out potential and different ability to undergo specific interactions. Liquid-liquid equilibrium phase diagrams were established, and partition experiments were conducted to evaluate extraction efficiency. Different partition patterns were obtained for studied pesticides, with [Ch][DHP] demonstrating the highest efficiency exceeding 90 % for each target pesticide due to its strong salting-out ability. On the other hand, more diverse partition trends due to specific interactions were obtained for low-melting cholinium-ILs ABS. The effect of pH and temperature on the partitioning behavior in [Ch][Ac]-based ABS highlighted the cholinium ILs extraction system's customizable nature. Focusing on [Ch]Cl for its eco-friendly aspects, widespread availability and excellent extraction performance, we optimized parameters for the removal of pesticides from real samples, applying the technology to spiked agricultural wastewater with an extraction efficiency of over 99 %. Our findings demonstrate the potential of cholinium-based IL-ABS in reducing environmental pollution through efficient pesticide extraction.

AB  - Polyphenols are natural compounds with enhanced antioxidant properties. They are present in relatively high concentrations in fruit/vegetable by-products. Therefore, there is a need for the development of efficient and cost-effective methods for the separation and purification of these valuable compounds. Traditional extraction with organic solvents needs to be switched to novel methods that are more efficient, with reduced extraction times and low consumption of organic solvents. Aiming at developing sustainable processes for the separation and purification of phenolic compounds, we used three model compounds, namely resveratrol, quercetin, and gallic acid, to investigate ionic liquid-based aqueous biphasic systems (IL-ABSs) formed by choliniumbased IL in combination with polypropylene glycol with a molecular mass of 400 g/mol (PPG400). The ABS composition in the two-phase region was selected according to a previously determined phase diagram. Extraction studies indicated the preferential partition of resveratrol and quercetin toward the hydrophobic PPG-rich phase that is mainly dominated by its hydrophobic nature and the strong salting-out effect of ILs. On the other hand, due to its considerably hydrophilic nature, gallic acid preferentially migrates toward the IL phase. The achieved results from grape stem extract demonstrated high extraction efficiencies of cholinium dihydrogen phosphate (~99% for resveratrol for the PPG phase and 78% for gallic acid for the IL phase), with considerable selectivity, demonstrating promising outcomes for potential applications.

AB  - Adsorption is a prevalent method for removing pollutants from the environment due to its efficiency in capturing contaminants from aqueous solutions. However, it comes with limitations such as the saturation of adsorbent materials, reducing their efficacy over time. Regeneration methods developed thus far often demand high temperatures or involve the use of hazardous chemicals, rendering them unfavourable for practical application. Pesticides, being significant pollutants with detrimental effects on both health and ecosystems, are frequently targeted for removal using adsorption techniques. Ionic liquids have emerged as promising compounds due to their advantages as green solvents, displaying thermal stability and non-volatility among other benefits. In this study, a regeneration process was conducted on carbon adsorbent material previously used to adsorb organophosphate pesticides: malathion, chlorpyrifos, and azinfos methyl. In this study series of different ionic liquids were synthesised for this purpose, by altering combinations of cations and anions, which aligns with the fundamental concept of ionic liquids as designer solvents. The results indicated an impressive regeneration efficiency for some types of ionic liquids, achieving up to 100% recovery of the adsorbent material. Ionic liquids such as TBPSal (tetrabutylphosphonium salicylate), bbimSal (1,3-dibutylimidazolium salicylate) and bbimBr (1,3-dibutylimidazolium bromide) proved to be among the most effective. This study underscores the importance of zero-waste and circular methodologies while stressing the pivotal role of adsorption and subsequent regeneration techniques in effectively eliminating pesticides from the environment. Employing eco-friendly chemicals like ionic liquids and accomplishing complete material recovery are fundamental strides toward sustainable approaches for pollutant eradication.

AB  - The drastic increase in pesticide usage over recent decades has significantly impacted environmental quality and is a considerable risk to human health and the ecosystem. Notably, organophosphate pesticides (OPs) like malathion, chlorpyrifos, and azinphos-methyl are among those extensively found in various environmental matrices. Their persistence and toxicity underscore the importance of eliminating pesticides from water sources. Ionic liquid- based biphasic aqueous systems (IL-ABS) have proven to be highly efficient in the extraction of pollutants from the environment including pesticides. The optimisation of extraction using such systems is of great importance in environmental remediation and purification processes. Through systematic optimisation, it becomes feasible to enhance the efficiency of IL-ABS in the extraction of pollutants. Optimisation techniques involve a comprehensive assessment of various parameters, such as TLL (tie line length) and mixture composition along the same TL. These parameters significantly impact selectivity and partitioning during extraction. For this purpose, TBPSal (tetrabutylphosphonium salicylate)/C6H5Na3O7 (sodium citrate) based ABS was optimised by varying either salt (different tie lines) or IL (on the same tie line) mass concentration. Longer tie lines led to increased extraction efficiencies by varying C6H5Na3O7 concentrations which influenced the partitioning of OPs, resulting in notable improvements (reaching 100% extraction efficiency). Also, the phase ratio variations notably affected recovery efficiencies. Systems with lower upper phase volumes are operationally and economically advantageous, minimising constituent usage during scale-up extraction processes. In this study, successful optimisation of pesticide extraction was achieved and significant advancements in extraction efficiency were attained. These findings not only confirm the feasibility of pesticide extraction but also underscore the importance of optimisation in such processes.

Ionic liquid- based biphasic aqueous systems (IL-ABS) have proven to be highly efficient in the extraction of pollutants from the environment including pesticides. The optimisation of extraction using such systems is of great importance in environmental remediation and purification processes. Through systematic optimisation, it becomes feasible to enhance the efficiency of IL-ABS in the extraction of pollutants. Optimisation techniques involve a comprehensive assessment of various parameters, such as TLL (tie line length) and mixture composition along the same TL. These parameters significantly impact selectivity and partitioning during extraction. For this purpose, TBPSal (tetrabutylphosphonium salicylate)/C6H5Na3O7 (sodium citrate) based ABS was optimised by varying either salt (different tie lines) or IL (on the same tie line) mass concentration. Longer tie lines led to increased extraction efficiencies by varying C6H5Na3O7 concentrations which influenced the partitioning of OPs, resulting in notable improvements (reaching 100% extraction efficiency). Also, the phase ratio variations notably affected recovery efficiencies. Systems with lower upper phase volumes are operationally and economically advantageous, minimising constituent usage during scale-up extraction processes. In this study, successful optimisation of pesticide extraction was achieved and significant advancements in extraction efficiency were attained. These findings not only confirm the feasibility of pesticide extraction but also underscore the importance of optimisation in such processes.",

AB  - Aqueous biphasic systems based on Ionic Liquids (IL-ABS) have gained considerable attention as extraction media for metal extraction and separation due to their improved adaptability in terms of specific interactions and environmentally friendly properties. In this regard, the creation of functionalised and task-specific ionic liquids has become essential for the production of effective and selective ABS. Phosphonium-based ionic liquids (ILs) have proven to be promising candidates for various applications due to their unique properties such as non-volatility, low toxicity, combination possibilities with different anions and thermoresponsiveness. This work focuses on the synthesis and characterisation of two novel hydrophilic phosphonium-based ILs with anions derived from natural acids that are well-known complexing agents, including acetate and glycolate. The aim of the work is to investigate the liquid-liquid equilibria of a ternary aqueous two-phase system by determining the phase diagrams at different temperatures. Ammonium sulphate was chosen as the second ABS component due to its acidic pH, low cost and wide availability as a salting-out agent. The phase diagrams were determined using the proven cloud point method at 25°C and 35°C, while the compound lines were determined analytically to gain insight into the exact composition of the phases. These parameters are very important in order to select the operating conditions for a possible application in metal recovery. The results obtained from the phase diagrams show that the formation of ABS is favoured in the following order of anions: Acetate < Glycolate. Glycolate-based phosphonium ILs showed a higher ability to form ABS, while the acetate IL is the most hydrophobic, resulting in a lower to salt out ammonium sulphate. These results indicate that the choice of anionic species in the development of phosphonium-based ionic liquids plays a crucial role in the formation of ABS as well as in their future application.

AB  - Lithium-ion batteries have become an integral part of the modern world: they power most of the portable devices we surround ourselves with every day. Almost all commercial lithium-ion batteries use graphite as the anode and metal oxides (cobalt, nickel, or manganese) or iron phosphate as the cathode material. However, compared to sodium, for example, the first alkali metal in the periodic table, lithium is far less abundant in the earth's crust. The situation is similar with elements needed for electrodes, such as cobalt, nickel, copper and even phosphorus, which are contained in cathodes and electrolytes. One of the solutions to reduce the negative aspects of global lithium demand is certainly recycling, which would contribute significantly to reducing the environmental impact. In the case of cobalt, copper and nickel, 90% of the material can currently be reused, while the proportion of lithium that can be recovered through recycling is around 65%. The work aims to investigate, develop, and optimise a separation method based on aqueous biphasic systems with non-toxic green solvents - ionic liquids and salt - for the extraction and separation of lithium and cobalt metals with the aim of their reuse. Two ionic liquids with the same cation and different anions (Acetate and Glycolate) with ammonium sulphate were used to build aqueous biphasic systems. The metal concentrations were determined using the ICP OES method and the extraction parameters (extraction efficiency) were calculated on this basis. Acetate and glycolate are relatively similar anions, with the glycolate anion containing a hydroxyl group. The results showed a higher efficiency of cobalt extraction (73.8%) when the system contains an ionic liquid with glycolate anion, while the efficiency extraction of lithium (72.8%) is higher when the system contains an acetate anion.
