Poly(acrylamide/styrenesulfonic acid) hydrogels for effective removal of Cr(III) ions.

ABSTRACT: Techniques for chromium ion removal have been researched more and more because of the significant harm to human health posed by this hazardous contamination in water. The present work represents the preparation of poly[acrylamide(Acr)/styrenesulfonicacid sodium salt (Sty)] hydrogels by free radical cross-linking polymerization applying various Acr and Sty monomer molar ratios. To produce Cr-poly(Acr/Sty) chelates, the produced hydrogels were examined for adsorption and desorption tests towards Cr(III) ions. The resulting hydrogels displayed a significant capacity for Cr(III) ion adsorption. Notably, the amount of Sty monomer in the hydrogel has a substantial effect on the Cr(III) ion capturing capacity. Cr-poly(Acr/Sty) and poly(Acr/Sty) hydrogels were characterized by modern analytical te
