Transport of Metallic Ions through Polyaniline-containing composite membranes

The extraction of Na+, Ni2+, and Cr3+ using six different membranes made of polyaniline composited with high-impact polystyrene, which differ in the doping agent and/or the preparation method, has been investigated. The swelling and ion-exchange capacities of the six polyaniline composited with high...
