Abstract: 
Backgrounds and Objectives: Hexavalent Chromium is an important contaminant in surface and ground waters and removal from contaminated water and waste water has received interest in recent years. Modified Zeolite with cationic surfactant can remove Cr(VI) from contaminant water. The aim of this research is investigation of Cr (VI) removal from aqueous solutions and its effective parameters by using Modified Zeolite with cationic surfactant.Materials and Methods: In this research the efficiency of Cr(VI) removal and impact of the important parameters including adsorbent dose, pH and contact time in the batch system was studied.Results: The results of this research showed that SMZ can remove more than 90 * Cr(VI) in the concentration 0.1-1.25 mg/l with optimum dose 0.3 gr and pH=6 120 minute in contact time.Conclusion: Modified natural zeolite have significant potential inCr(VI) removal fromcontaminated water.Maximumpercent removal of Cr(VI) was in the pH=6 and 120 minute contact time.Adsorption data in the equilibrium was fitted with Langmuir isotherm. Separation factor was between 0 and 1 that indicates the favorable condition for Cr(VI) adsorption on the SMZ.
