Considering the water resources constraints, population increase, industry growth and increase of industrial wastewater, access to safe water is one of the biggest problems in every society. Chemical pollutants that naturally or through human activities enter the water, are one of the most important pollutants of water. A group of these pollutants which have become a global dilemma are heavy metals. Heavy metals are considered as toxic and persistent pollutants in the environment and cause a wide range of effects for loving organisms. There are various techniques for removing heavy metals from water. Advantages of adsorption process in comparison to other removal methods, include the cost effective, adsorbent recovery capability and non-sludge production. Among adsorbent minerals, zeolites are the most promising adsorbents. Zeolites are porous crystalline aluminosilicate consisting of the first and second group elements. The purpose of this study is the removing of lead and cadmium from aqueous solutions using synthesized zeolite type of 13X from stone cutting sludge. Characteristics of synthesized zeolite were determined using the XRD, SEM, EDS and BET analysis. Adsorption experiments were designed in the both batch and column and parameters effecting adsorption including pH (2, 3, 4, 5, 6, 7), amount of adsorbent (0.1, 0.5, 1, 2, 4 g/l), equilibrium time (1, 5, 15, 30, 60, 120 min) and initial concentration of metals (1, 5, 10, 25, 50, 100 mg/l) were investigated. The results showed that the optimum pH for Cd +2 and Pb +2 adsorption was 6 and 5, respectively.Minimum adsorption for both metals was at pH 2. With increase of the amount of adsorbent from 0.1 to 2 g/l, the adsorption percentage of cadmium and lead were obtained 96% and 99%, respectively. Maximum adsorption ofCd +2 andPb +2 at 30 and 15 minutes were 95% and 96%, respectively. Study of adsorption kinetics also represented better fit to the pseudo-second-order kinetics for adsorption of both metals. Maximum adsorption of Cd +2 and Pb +2 was at initial concentration of 10 and 25 mg/l, respectively. Cd +2 and Pb +2 adsorption was fitted better by Langmuir isotherm models than the Friundlich model. Maximum adsorption ofCd +2 andPb +2 was 62 and 70 mg/g, respectively; wich was consistent with maximum adsorptionproposed by the Langmuir model. Column experiments showed that the zeolite sorption performance was 56% (amount of adsorption 28 mg/g) for Cd +2 and 60% (amount of adsorption 30 mg/g) for Pb +2 . It has the high desorption ability up to 90% by HNO 3 0.1 M for both metals. Hence it is possible to apply this adsorbent in successive adsorption cycles. Results of adsorption from textile wastewater sample using zeolite showed that the removal ofCd +2 andPb +2 was 69% and 78%, respectively. The produced zeolite showed the sorption efficiency comparable with commercial zeolite 13X. Keywords: Adsorption, Synthesized zeolite, Lead, Cadmium, Adsorption isotherm
