Abstract: Adsorption performance of the intercalated bentonite composite materials to acid blue was researched.The effect of the ratio of the organic bentonite and intercalated materials carbonymethyl chitosan,intercalation reaction temperature,drying temperature and adsorption time on the absorbent properties was discussed.The experiment indicated that the adsorption rate of the intercalation bentonite composite materials to the acid blue reached 93 % in the condition of the ratio of the organic bentonite and interc...
