Removal of copper (II) ion from aqueous solution using copolymer of acrylic acid and acrylamide

Abstract

Cross linked copolymers of acrylic acid(sodium acrylate) and acrylamide hydrogel was
studied for capture of copper ion from aqueous solution .The batch experiment was
conducted to evaluate the effect of system variables .The effect of the pH and contact time
have been studied at room temperature .The optimal pH value of Cu(II)removal by polymer
was 7.0 . The adsorption kinetic data was analyzed using pseudo-first order, pseudo-second
order, and Elovich models. The adsorption kinetic was found to follow pseudo- second order
rate model, due to the high correlation coefficient and agreement between the experimental
and calculated value of qe.
