Abstract
The chelating ion-exchange properties of the methylmethacrylate (MMA)-8-quinolinyl acrylate (8-QA) copolymers, synthesized using different monomer feed ratios, were estimated by batch equilibration method. Five metal ions viz., Cu+2,Ni+2,Co+2, Zn+2 and Fe+3 were used to evaluate the capability of MMA-8-QA copolymers as a cation exchangers. The ion-exchange study was carried out under three different experimental variables viz., pH of the aqueous medium, electrolyte and its ionic strength and shaking time. It was observed that due to the presence of a pendant ester-bound quinolinyl group, the copolyraers are capable of exchanging the tested cations from their aqueous solutions.
