    Abstract


    Magnetic CoFe2O4/bentonite nanocomposite was synthesized by chemical co-precipitation method. It has a large surface area of 380 m2/ g. Absorption ability of CoFe2O4/bentonite was studied on methylene blue solution. The factors that affected the absorption process, such as absorption time, temperature and pH were researched. The results showed that at 50mg/l of methylene blue solution and pH= 7-8, the absorption efficiency of CoFe2O4/bentonite for methylene blue was highest with the value of 95,0 -95,1%
