چکیده    This work, the application of a surfactant-modified natural nano-clinoptilolite for the removal of several two valances heavy metal cations (i.e., cu^2+, pb^2+, ni^2+, cd^2+, fe^2+ and zn^2+) from aqueous media was discussed. 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.
