Adsorptive Separation of Lead and Zinc Ions by Novel Type of Calix[4]arene Carboxylate Resin Immobilized with Polyallylamine

Abstract

Abstract Novel type of calix[4]arene carboxylate resin immobilized with polyallylamine has been prepared to investigate the adsorption behavior for lead and zinc ions. It was found that the resin possesses significantly higher separation efficiency for lead away from zinc. In the separation by means of column chromatography, it was confirmed to highly selectively adsorb trace amount of lead ion over large excess amount of zinc ion.
