摘要

CTMAB-vermiculite, which can improve the vermiculite interlayer space and adsorption capacity of organic matter, has been obtained by using cetyltrimethylammonium bromide. The effects of the dosage of material, shaking time, the concentration of methyl orange, and the pH on the absorbent characteristics of methyl orange are studied by spectrophotoscopy. The structural characteristics of vermiculite and CTMAB-vermiculite have been studied through SEM. The results show that CTMAB-vermiculite changes dramatically ~ its interlayer space becomes larger. The methyl orange removal rate of CTMAB-vermiculite is better than that of vermiculite. In about 30minutes. CTMAB-vermiculite can reach absorption equilibrium. Low pH conditions are conducive to CTMAB-vermiculite adsorption of methyl orange. The activated temperature should be controlled under the initial decomposition temperature of CTMAB, which can improve the reusability of recycled vermiculite.
