Removal of uranyl ions in aquatic mediums by using a new material: Gallocyanine grafted hydrogel
(ELSEVIER SCIENCE BV, 2013)
A new material containing gallocyanine (GC) grafted polyacyril amide (PAA) was synthesized and its adsorption ability was examined for the removal of uranyl ions from aqueous media. The new developed adsorbent was characterized ...
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 ...
Removal of UO22+ from Aqueous Solutions by Maleic Anhydride-Styrene-vinyl acetate Terpolymer Modified with Ethylenediamine and Diethylenetriamine
(ASIAN JOURNAL OF CHEMISTRY, 2013)
Maleic anhydride-styrene-vinyl acetate (MA-S-VA) terpolymer was prepared. It was modified by ethylenediamine (EDA) and diethylenetriamine (DETA) in order to get cross-linked polymers bearing carboxyl and amine groups. They ...
Synthesis of a Useful and Economic Polymeric Material for Effective Removal of Bisphenol A
(SPRINGER/PLENUM PUBLISHERS, 2018)
A composite material containing polyacryl amide (PAA) and lignin (L) was developed and characterized for effective Bisphenol A (BPA) removal. Fundamentals of the proposed approach is based on adsorption of BPA molecules ...
Synthesis and characterization of a composite polymeric material including chelating agent for adsorption of uranyl ions
(ELSEVIER SCIENCE BV, 2017)
In this study, a versatile polymeric material was synthesized by grafting Calcon Carboxylic Acid (CCA), which is known as a chelating agent for some metal ions, to polyacrylamide (PAA) structure. Thus, the adsorptive ...
Adsorption properties of lignin containing bentonite-polyacrylamide composite for UO22+ ions
(TAYLOR & FRANCIS INC, 2016)
As a new material, a composite of polyacrylamide (PAA)-Bentonite (B) containing Lignin (L) was synthesized and adsorption properties of this new material was studied for the removal of uranyl ions from solution. The material ...
Amine-modified maleic anhydride containing terpolymers for the adsorption of uranyl ion in aqueous solutions
(SPRINGER, 2013)
Maleic anhydride-styrene-methyl methacrylate (MA-S-MM) terpolymer was prepared. It was modified by ethylenediamine (EDA) and diethylenetriamine (DETA) in order to get cross-linked polymers bearing carboxyl and amine groups. ...
Organoclay modified with lignin as a new adsorbent for removal of Pb2+ and UO2 (2+)
(SPRINGER, 2014)
This study investigated a new adsorbent prepared from lignin modified organoclay for the removal of Pb2+ and UO2 (2+) from aqueous solutions. The characterization of new adsorbent was performed by FT-IR and XRD. Adsorption ...
