Triton X-100 was used as modifier and to achieve maximum efficiency of adsorption; variables such as the concentration of surfactant, contact time, the working temperature and pH of sample solution were optimized. The results revealed that, the maximum adsorption was achieved at a solution with the pH of 6, containing 2 mL of triton X-100 and 2 g/L of clinoptilolite at 45 °C. The obtained selectivity series for the adsorption of cations were Pb 2+ >Cu 2+ >Cd 2+ >Ni 2+ >Zn 2+ >Fe 2+ . The maximum adsorption capacity of the modified zeolite for Pb 2+ , Cu 2+ , Cd 2+ , Ni 2+ , Zn 2+ and Fe 2+ was 91.34, 85.71, 78.27, 76.18, 67.41 and 63.45 mg/g, respectively. The adsorption data were acceptably fitted to the both Freundlich and Langmuir isotherms. Heavy metal removal Nano water treatment-clinoptilolite Surfactant G R A P H I C A L A B S T R A C T
