Removal of Nickel from Aqueous Solutions by Natural Bentonites from Slovakia
(Materials, 2021)
In this study, the removal of nickel (Ni(II)) by adsorption from synthetically prepared solutions using natural bentonites (Lieskovec (L), Hliník nad Hronom (S), Jelšový Potok (JP), and Stará Kremnička (SK)) was investigated. ...
Effective removal of Reactive Orange 16 dye from aqueous solution by amine-functionalized sepiolites
(Desalination and Water Treatment, 2019)
Natural and acid-activated sepiolites, functionalized by covalent grafting of [3-(2-aminoethylamino) propyl]trimethoxy-silane were used as adsorbents for the removal of an anionic Reactive Orange 16 dye from aqueous ...
Exploring UiO-66(Zr) frameworks as nanotraps for highly efficient removal of EDTA-complexed heavy metals from water
(Journal of Environmental Chemical Engineering, 2021)
Metal-organic frameworks (MOFs), an exciting class of porous crystalline materials, are suitable for adsorptive removal of toxic heavy metal-ethylenediaminetetraacetic acid (M-EDTA) complexes from wastewater. In this paper, ...
Facile Upcycling of Hazardous Cr-Containing Electroplating Sludge into Value-Added Metal–Organic Frameworks for Efficient Adsorptive Desulfurization
(ACS Sustainable Chemistry and Engineering, 2020)
The recycling of heavy metals from solid wastes and transforming these metals into useful materials, such as metal oxides, nanocomposites, and metal–organic frameworks (MOFs), are beneficial for both sustainable development ...
Technetium removal from the aqueous solution using zeolites A and Y containing transition metal ions Co2+ and Zn2+
(Journal of Radioanalytical and Nuclear Chemistry, 2018)
The adsorption properties of two zeolite types, faujasite (NaY, ZnY, CoY) and LTA-4A zeolite (NaA, ZnA, CoA), towards technetium were studied in batch static experiments. The Si/Al ratio, acidity, dealumination, chargebalance ...
Efficient multistep arsenate removal onto magnetite modified fly ash
(Journal of Environmental Management, 2018)
The modification of the fly ash (FA) by magnetite (M) was performed to obtain FAM adsorbent with improved adsorption efficiency for arsenate removal from water. The novel low cost adsorbents are characterized by liquid ...
Multifunctional use of magnetite-coated tuff grains in water treatment: Removal of arsenates and phosphates
(Advanced Powder Technology, 2019)
Natural filtration material tuff (T) was modified by coating with nano-sized magnetite. The grain fraction of 0.6–1.9 mm was submitted to hydrothermal synthesis of magnetite. Thus formed magnetite modified tuff (MMT) was ...
Organically modified montmorillonite as an environmental adsorbent of pollutants: Formaldehyde from urea-formaldehyde resin and Acid Red 183 dye from the aqueous solution
(Journal of Environmental Chemical Engineering, 2024)
In this research, a composite based on montmorillonite (K10) modified with HDTMABr was used. The characterization of the pure K10, NaMMT and OMMT was performed using XRD, FTIR-ATR, SEM, TG, DTG, and DTA. Ion exchange ...
In situ synthesis of potassium tungstophosphate supported on BEA zeolite and perspective application for pesticide removal
(Journal of Environmental Sciences, 2019)
Potassium tungstophosphate is supported on BEA zeolite by in situ synthesis for glyphosate removal. Spectroscopic measurements identified hydrogen bonding as a primal interaction of potassium salt and BEA zeolite. Composites ...
Mitigating toxicity of acetamiprid removal techniques – Fe modified zeolites in focus
(Journal of Hazardous Materials, 2022)
All remediation pathways in aqueous solutions come down to three dominant ones - physical, chemical, and combinations thereof. Materials proposed for adsorption and oxidative degradation can induce positive or negative ...
