Abstract

ABSTRACT: In this study, uranyl ion adsorption from aqueous solutions has been investigated by highly swollen gelatin and poly(vinyl alcohol) based semi-interpenetrating polymer network systems of acrylamide/sodium acrylate. For this, chemically cross-linked copolymer of acrylamide/sodium acrylate hydrogels with gelatin and/or poly(vinyl alcohol) were prepared by free radical polymerization in an aqueous solution of acrylamide and sodium acrylate using ammonium persulfate/N, N, N′, N′-tetramethylethylenediamine as redox initiating pair in the presence of poly(ethylene glycol)diacrylate as a cross linker. Adsorption studies were investigated by spectrophotometric method at 25°C. Sorption capacity, removal efficiency, and partition coefficient of the hydrogels were investigated. Removal efficiency was changed within a range of 7.06–33.03%. GRAPHICAL ABSTRACT:
