交联粘土矿物的吸附特性研究(Ⅲ)——改性膨润土对水中酚吸附性能研究

Study on Adsorption Properties of Cross-Linked Clay Minerals —Adsorption of Modified Bentonite for Phenol in Waste Water

探讨经Ａｌ（ＯＨ）０．５＋２．５，Ｈ２ＳＯ４处理的膨润土对废水中酚吸附性能和处理效率，结果表明：最高去除率为７３．８８％．处理水再经活性炭吸附处理，总去除率达９９．８％，酚含量可降至０．５ｍｇ／ＬＨ２Ｏ，达到国家排放标准．

Adsorption properties of the Bentonite treated with Al(OH) 0.5+ 2.5 or H 2SO 4 or CTMAB for phenol in water are studied in this paper.The results showed that through adsorption with both modified bentonite and active carbon,phenol content in waste water,descended below 0.5 mg/L,accores with the drain standard of waste water.The adsorption efficiency is up to 99.8%.
