| 摘 要： | 研究了用聚二甲基二烯丙基氯化铵(PDMDAAC)改性凹凸棒土对微污染水中苯酚的吸附性能、影响因素及其再生后吸附效果.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 adsorptive ability and influencing factors of the attapulgite modified with poly dimethyldiallyl ammonium chloride(PDMDAAC) for removing phenol from slightly polluted water was investigated.In addition,the adsorption effect of regenerate modified attapulgite was also investigated.The result showed that this modified attapulgite possessed stronger ability for adsorption of the phenol in slightly polluted water:the adsorption removing rate amounted to 89% when pH was 6-8,phenol concentration-100 mg/L,addicting amount of modified attapulgite-40 g/L,and adsorption time period-40 min.The modified attapulgite after adsorption operation could be regenerated with alkali and its adsorption power would not decrease noticeably.Static adsorptive behavior of modified attapulgite was consistent with that described by Freundlich adsorption isothermal equation. |
