چکیده:

Polyaniline (PANI) adsorbents functionalized with zinc oxide nanoparticles (ZnO-NPs) and Cobalt Hexacyanoferrate (CoHCF) were prepared by chemical precipitation method and their applications for adsorption of Cd(II) and Pb(II) from aqueous solutions were investigated. The adsorbents were characterized by FTIR analysis. FTIR analyses of adsorbents indicated that the ZnO and CoHCF groups have been introduced successfully into the PANI. The adsorption percentage of Cd2+ and Pb2+ onto CoHCF@PANI/Nc is higher than ZnO@PANI/Nc and bare PANI. Increasing concentration of CoHCF and ZnO in PANI has increased metal ions adsorption to more than 56 and 34%, respectively.The formation particles in nanoscale of CoHCF@PANI/Nc (the best adsorbent), Confirm by the TEM image with average size of 30 nm.
