摘要
凹凸棒粘土经溴化十六烷基三甲胺（ＣＴＭＡＢ）改性后，对水中酚具有较强的吸附能力，苯酚浓度为１００ｍｇ／Ｌ时，加入量为４％，ｐＨ为８．０时，去除率达到８８．５％，且有机凹土经再生后可反复使用。吸附平衡浓度与吸附量关系符合Ｆｒｅｕｎｄｌｉｃｈ吸附等温式。
The attapulgite modified by CTMAB has a good adsorption capacity when it is used to absorb phenol about 100 mg/L in water.In the condition of pH8.0,the removal rate of phenol can reach 88.5% when it is added at 4%dosage.The relationship between absorption quantity and equilibrium concentration is fit for Freundlich isothermal adsorption.
