摘　　要：采用自制有机改性膨润土对水中苯酚进行吸附研究,探讨了吸附时间、吸附溶液的pH值、吸附溶液浓度等因素对吸附效果的影响.结果表明,改性后的有机膨润土能有效吸附水中的苯酚,有机改性膨润土改善了其微观结构,提高了膨润土的吸附能力和离子交换能力.The adsorption of phenol by organobentonite was researched. The effects of adsorption time, pH value and anion-positive ion on adsorption efficiency were examined. The test results indicated that organobentonite could effectively adsorb phenol. After modification treatment, the property of organobentonite was improved, and the capacities of adsorption and ion-exchange were increased. The method of regeneration of organobentonite was good.
