Compexing properties of the cation-exchangers with grafted carboxylic moieties

Abstract

The complexing properties of the carboxylic sorbents such as CM-52, Olvagel-COOH, MacroPrep 50 CM and hyper cross-linked polysterene MN towards Cu2+, Co2+, Ni2+, Cd2+, Zn2+, Mn2+ and Pb2+ were systematically studied. The optimal conditions for sorption of the metal ions from solutions were determined; the pH influence on the metal ions recovery was studied. The maximum recovery of the ions from the solutions is reached at pH higher than 5-6, but at pH lower than 2 the ions are quantitatively desorbed. The sorbent Olvagel-COOH is the most selective towards the studied ions.
