Application of polypyrrole and polypyrrole/polyethylenimine for the removal of some heavy metal ions from aqueous solution / Samira Hosseini

Polypyrrole (Ppy) prepared by chemical oxidation using FeCl3 as the oxidant has exhibited 100% sorption capacity for the removal of heavy metal ions (Pb, Ni, Cu, Cd and Zn) from aqueous solutions. Batch adsorption results showed that solution pH had a major impact on metal adsorption. 100% heavy met...
