| 摘 要： | 实验研究了用聚二甲基二烯丙基氯化铵(PDMDAAC)改性凹凸棒土吸附微污染水中苯酚的性能及主要影响因素.结果表明:PDMDAAC改性凹凸棒土对微污染水中苯酚具有较强的吸附能力,在pH=6～8、苯酚浓度为10 mg/L、投加量为40 g/L、吸附时间40 min的条件下,吸附去除率达89%;改性后的凹凸棒土可用碱进行再生,再生后对苯酚的吸附能力没有明显下降,改性凹凸棒土的静态吸附行为符合Freundlich吸附等温方程.

| Abstract: | The performance of adsorption, influencing factors and adsortive effect after regeneration for removing phenol trom micro-pulluted water by PDMDAAC-attapulgite were investigated. The results showed that the adsorption of phenol by PDMDAAC-attapulgite was better and the removal efficiency of the PDMDAAC-attapulgite could reach 89%. PDMDAAC-atapulgite could be regenerated with alkali and the removal efficiency after the regeneration did not drop obviously. The behavior of adsorption could be discussed by Freundlich equation satisfactorily. |
