Two following reason lead (Pb) us to find a way for removing heavy metals (HM) from the water resources, first limitation of water resource and increasing of water scarcity and second increaseing of surface and groundwater contamination by HM, (derived from industrial and municipal wastewater). In this research, Zeolite (Clinoptilolit) as natural and Amberlite (IR-120) as chemical were used as sorbents of Pb. Experiments were done in batch mode under various operational conditions including three size of zeolite and one mean diameter of Amberlite. An splite-plot experimental design was employed with 60 treatments and three replications at Shiraz University, Shiraz, Iran in 2011. The treatment were five different concentration of the Pb contamination and three size of zeolite (0.075, 0.2 and 0.42mm). The concentration for Pb were: 40, 250, 500, 1000. The removing efficiency of the zeolite and Amberlite was measured for Pb. The results showed that the effect of concentration of contamination and zeolite size were statisticaly significant. It showed that by increasing of the concentration of contamination, absorption of the HM increases linearly by zeolite. Maximum Pb absorption occurred at 1250 mg/l with a value of 59.97 mg for 1 grams of zeolite. The minimum Pb absorption occurred at 40 mg/l with a value of 1.82 mg for 1 grams of zeolite. The results showed that the effect of concentration of HM were statisticaly significant for Amberlite and it also observed that the absorption of HM by Amberlite increases linearly. Maximum Pb absorption occurred at 1250 mg/l with a value of 62.35 mg for 1 grams of Amberlite. The minimum Pb absorption occurred at 40 mg/l with a value of 1.98 mg for 1 grams of zeolite.
