Different parameters effect like contact time, pH, adsorbent dosage, initial concentration and adsorption isotherms will be examined. XRD and SEM methods are used to identify characterization of synthesized adsorbent. The pseudo first/second order were employed to evaluate the process kinetics. The results show that Batch kinetic data are in good agreement with the pseudo second order model. The adsorption data for Cr(III), Pb(II), Zn(II), Cd (II) and Ni(II) have been well fitted by Freundlich isotherm model. The adsorption efficiency of zeolite at optimum condition for Cr(III), Pb(II), Zn(II), Cd (II) and Ni(II) were equal to 93.4, 86.1, 89.9, 93.6 and 83.3%,respectively.
