| 摘 要： | 考察了苯酚初始浓度、投加量、溶液pH值、吸附温度及吸附时间对改性凹凸棒土吸附废水中苯酚性能的影响。结果表明:当苯酚溶液初始浓度为30 mg/L,pH为6.5~7.5,壳聚糖改性凹凸棒土投加量为2g/25mL,吸附温度为35℃以及吸附时间50min时,苯酚的去除率达到89.0%。通过吸附等温试验探讨了改性凹凸棒土的改性效果及其吸附机制,为凹凸棒土吸附含酚废水的研究提供理论依据。

| Abstract: | The effects of initial concentration of phenol, dosage of modified attapulgite,pH of the solution,adsorption temperature and adsorption time on the adsorption capacity of the modified attapulgite were studied in the experiment. Results showed that the phenol removing rate reached 89.0%,when the optimum conditions were initial concentration of phenol 30mg/L,pH of the solution 6.5-7.5,dosage of modified attapulgite 2g/25mL,adsorption temperature 35~（2 and adsorption time 50 min.The modification effect of the modified attapulgite and the mechanism of adsorption were discussed by adsorption isothermal curves.It provided the theoretical basis for the adsorption of the modified attapulgite for phenol. |
