| 摘 要： | 研究了Fenton试剂联合聚二甲基二烯丙基氯化铵（PDMDAAC）改性凹凸棒石对模拟微污染水中苯酚的去除效果。考察了pH值、反应时间、投加量、温度等因素对苯酚去除效果的影响。结果表明：先采用Fenton试剂氧化再用改性凹凸棒石吸附对微污染水中苯酚具有较好的去除效果，在pH=9、温度为25℃、改性凹凸棒石投加量为5g／L、吸附时间20min的条件下，苯酚去除率达98．2％。

| Abstract: | Removal of phenol in Micro-polluted water by combination of reagent fenton and attapalgite modified with polydimethyl diallylammonium chloride （PDMDAAC） technology was examined. The effects of the factors such as pH value, reaction time, dosages of modified attapulgite and temperature on the removal of phenol were studied. The results showed that the removal rate of phenol in Micro-polluted water was high by using fenton reagent for oxidation first and then followed by adsorption using modified attapulgite, of which the removal rate reached 98.2% at the conditions of pH value 9, temperature 25℃, dosage 5g/L of the modified attapulgite lasting 20 min for adsorption. |
