Abstract:

Adsorption of aqueous solution consist of heavy metal ions can be an effective process for the removal of heavy metal ions from aqueous solutions. In this study, the adsorption properties of polyaniline (PAn) for Zn2+ adsorption were investigated by using batch adsorption techniques. The effects of initial metal ion concentration, initial pH, temperature and contact time on adsorption efficiency were studied using response surface methodology. In the experiments the optimum condition was found out as pH=12.0, C0 = 10 ppm, T=20 ⁰C and t = 600 min. The results indicated that the polyaniline (PAn) is a suitable adsorbent for removing Zn2+ removing from aqueous solutions.
