Increasing of water scarcity on the one hand and increasing of water contamination, lead us to find a way for removing the heavy metals (HM) from the resources. In this research, Amberlite (IR-120) were used as sorbents of HM. Experiments were done with one diameter of Amberlite. A randomize experimental design was employed with 15 treatments and three replications. The treatment inclouding five different concentrations of NI, Pb and Cd. The concentration for Pd was: 40, 250, 500, 1000 and 1250 mg L-1 and 4, 6, 15, 20 and 40 mg L-1 for Ni and Cd. The removing efficiency of the Amberlite was measured for Pb and Cd. The results showed that the effect of concentration was statistically significant for Amberlite. It was also observed that the absorption of HM by Amberlite increases linearly. Maximum Pb, Ni and Cd absorption occurred at 1250, 40 and 40 mg L-1 with a value of 62.35, 1.98 and 1.99 mg for 1 grams of Amberlite, respectively. The minimum Pb, Ni and Cd absorption occurred at 40, 4 and 4 mg L-1 with a value of 1.98, 0.19 and 0.19 mg for 1 grams of Amberlite, respectively
