... Abstract The complexing properties of the carboxylic sorbents such as CM-52, Olvagel-COOH, MacroPrep 50 CM and hyper cross-linked polysterene MN towards Cu 2+ , Co 2+ , Ni 2+ , Cd 2+ , Zn 2+ , Mn 2+ and Pb 2+ 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. ...
