Uranium and lead adsorption onto bentonite and zeolite modified with polyacrylamidoxime
(SPRINGER, 2012)
Polyacrylonitrile (PAN) and bentonite (B)/zeolite (Z)-PAN composites were prepared by direct polymerization of acrylonitrile (AN) and AN adsorbed onto B and Z. PAN and the composites were subjected to amidoximation procedure ...
Polyacrylamide-hydroxyapatite composite: Preparation, characterization and adsorptive features for uranium and thorium
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2012)
The composite of synthetically produced hydroxyapatite (HAP) and polyacrylamide was prepared (PAAm-HAP) and characterized by BET, FT-IR, TGA, XRD, SEM and PZC analysis. The adsorptive features of HAP and PAAm-HAP were ...
Equilibrium, thermodynamic and kinetic investigations for biosorption of uranium with green algae (Cladophora hutchinsiae)
(ELSEVIER SCI LTD, 2017)
Removal of toxic chemicals from environmental samples with low-cost methods and materials are very useful approach for especially large-scale applications. Green algae are highly abundant biomaterials which are employed ...
Adsorptive properties of sulfolignin-polyacrylamide graft copolymer for lead and uranium: Effect of hydroxilamine-hydrochloride treatment
(ELSEVIER SCIENCE BV, 2013)
Sulfolignin-polyacrylamide graft copolymer (PAAm-SL) was synthesized and its adsorptive features were compared with those of PAAm and PAAm-SL modified to their hydroxamic acid and amidoxime forms for Pb2+ and UO22+ ions. ...
Determination of uranium in water samples with chromogenic reagent 4-(2-thiazolylazo) resorcinol after ionic liquid based dispersive liquid liquid microextraction
(SPRINGER, 2016)
A simple extraction and spectrophotometric determination of trace amount of uranium was described. The method is based on complex formation between uranium and 4-(2-thiazolylazo)resorcinol (TAR), a well known ligand, ...
Separation of uranium and thorium in aqueous solution using polyhydroxyethylmethacrylate-hydroxyapatite novel composite
(DESALINATION PUBL, 2012)
Poly(hydroxyethylmethacrylate-hydroxyapatite) [P(HEMA-Hap)] composite was synthesized by free radical polymerization in aqueous solution. The adsorptive features of P(HEMA-Hap) composite were investigated for UO22+ and ...
Removal of radioactive elements from aqueous solutions by adsorption onto polyacrylamide-expanded perlite: Equilibrium, kinetic, and thermodynamic study
(ELSEVIER SCIENCE BV, 2013)
In this research, a novel composite, poly(aaylamide-expanded perlite) [P(AAm-EP)], was synthesized and its adsorptive features were investigated for UO22+ and Th4+ ions. The composite's adsorptive features were evaluated ...
Solid phase extraction of uranium on a new brush type graft copolymer and spectrophotometric determination of its in water samples
(SPRINGER, 2016)
A new versatile solid phase extraction and spectrophotometric determination of uranium (VI) was proposed with using poly(caprolactone-b-vinyl benzyl chloride-g-dimethyl amino ethyl methacrylate), poly(CL-b-VB-g-DMAEMA), ...
Uranium and thorium adsorption from aqueous solution using a novel polyhydroxyethylmethacrylate-pumice composite
(ELSEVIER SCI LTD, 2013)
Poly(hydroxyethylmethacrylate-pumice), [P(HEMA-Pum)], composite was synthesized by free radical polymerization in aqueous solution. The adsorptive features of P(HEMA-Pum) composite were investigated for UO22+ and Th4+ using ...
Feasibility of tetracycline, a common antibiotic, as chelating agent for spectrophotometric determination of UO22+ after cloud point extraction
(SPRINGER, 2014)
A cloud point extraction (CPE) procedure was presented for the preconcentration of UO22+ ion in different water samples. Tetracycline (TC) is the second most widely used antibiotics in the world and is used as chelating ...
