Zinc is one of the most important pollutants for surface and ground water. Because of its acuteToxicity and non‐biodegradability, zinc‐containing liquid and solid wastes are considered ashazardous wastes. In this study, polyaniline (PAn) nanoparticle was prepared in aqueoussolution by the polymerization of aniline using ammonium peroxydisulfate (APS) as oxidant inthe presence of surfactive dopant sodium dodecylbenzenesulfonate as surfactant. Thecapability of separating Zn(II) ions was studied. The results indicated that removal percentagewas increased by increasing the PH of solution, adsorbent dose and contact time.
