摘　　要：以C12阳离子烷基多糖苷季铵盐对膨润土改性制备有机膨润土,探讨了有机膨润土的制备因素对去除废水中苯酚效果的影响,结果表明,在有机改性剂/膨润土的质量比为40 mg/g,反应温度为30℃,pH=8的条件下,反应30 min制备的有机膨润土,对初始浓度为50 mg/L的含苯酚废水去除率达到89.50%,其对苯酚的吸附符合Freundish方程。The organic modified bentonite was synthesized by using the C12alkyl polysaccharide glucoside quaternary ammonium compound as modifier,the influence of organic modified bentonite factors on the removal of phenol had been studied,results showed that under the conditions of organic modifier/bentonite mass ratio was 40mg/g,temperature was 30 ℃,the value of PH was 8,the initial concentration of 50 mg/L of phenol wastewater,the removal rate reached 89.50 %.The Freundlich model was described the adsorption isotherm well.
