摘要
归纳总结了天然凹凸棒石与改性凹凸棒石吸附水中有机污染物的效果,分析讨论了凹凸棒石吸附水中有机污染物的机理、影响因素及吸附等温线,为以后本课题的相关研究提供参考。同时简述了凹凸棒石的基本性质和结构特点,介绍了凹凸棒石的改性方法,并展望了凹凸棒石在废水处理研究中的发展趋势。综述表明凹凸棒石吸附水中有机染料性能优异,吸附苯类、酚类效果也较理想,凹凸棒石改性后吸附效果更佳。
The adsorbing effects for organic pollutants in wastewater by attapulgite were generalized. The mechanism of absorption, effecting factors and isotherm were analyzed and discussed. This paper simply discribed the basic character and structure speciality of attapulgite, introduced the improving method and expected the development direction in the treatment of wasterwater. It can be supplied the reference for relative research in future. It was shown that adsorption of organic dyes by attapulgite had excellent performance, as well as the adsorption of benzene, phenols was rathter ideal.It was more better with using modified attapulgite.
