High chloride concentrations in freshwater can be harm for human, plants and aquatic organisms. Many techniques have been adopted to reduce the amount of chlorides in wastewater. Natural clays are abundantly available low-cost natural resource which is nontoxic to the ecosystem. In this research, we study two areas clay (Malek-Siah-Kouh and Hormak clay) as a sorbent for chloride ion removal. Quantitative measurments are accomplished by UV/Vis technique. The influential variables were studied on absorption including; rotation temperature, grain sizes, pH of the solution, adsorbent amount, initial concentration of chloride ion and contact time of the removal process. The optimum values of the rotation(al) speed, temperature, grain size, absorbent amount and the contact time for Malek-Siah-Kouh were estimated at 100rpm, 40 ° C, 200- 325, 0.4g and 15 min, and for Hormak were estimated at 100rpm, 30 ° C,
