Abstract: 
Organic pollutants of wastewaters have always been one of the most important environmental challenges. Absorption of contaminants from aqueous solution by nano-bentonite is an efficient way due to smaller size and increased surface area of the particles. In this study, bentonite prepared from bentonite mines of Kheirabad was purified by sedimentation method. Magnetic nano composite was synthesized by coprecipitation method. The properties of nanocomposite was studied using FTIR, XRD, VSM, BET and TEM analyses. The adsorption process of TCP, a toxic carcinogen phenolic derivative (initial concentration of 100 mg/L) by pure bentonite and magnetic nano composites (1 gr/L) was evaluated at pH= 5, 23-25 0C and different times. The results indicated that the percentage of adsorption of TCP by magnetized bentonite nano composite due to increased surface area (108. 73 m2 g-1) and magnetized nano particles in 60 minutes was attained %96. 777, compared to pure bentonite which adsorbed %68. 25 of TCP in 3 hours.
