Abstract

The successive Ni(II) adsorption and adsorbed-Ni(II) desorption experiments have been performed in order to clarify the repetitive heavy-metal-cation recovering functionality of p-Styrenesulfonicacidsodiumsalt/Acrylamide (p-SSAS/AAm) and Sodium acrylate/Acrylamide (SA/AAm) gels, and also to examine the effect of the terminal group in the side chain. It has been revealed that the SA/AAm gels show high recovering functionality usable in the actual applications while that the p-SSAS/AAm gels can be used in limited conditions.
