Selective adsorption of metallic complex using polyaniline or polypyrrole

Mechanism of adsorption of Cu(I)2−. This schematic drawing shows the mechanism of ion exchange of Cu(I)2− with the conducting polymers. The Cu(I)2− complex displaces the dopant anion (Cl−), thus remaining adsorbed on the composite. The adsorption of Cu(I)2− is more feasible with the PAni found in the M-PAni composite than with the PPy of the M-PPy composite.162
