改性海泡石在环境污染治理中的应用

Application of modified sepiolite in environmental pollution control

改性海泡石是一种纤维状富镁粘土矿物 ,其独特的层状结构和巨大的比表面使其具有吸附性强、离子交换能力大的特点 ,且具有二次污染小、可重复使用的优点 ,因此在污染治理方面的应用较为广泛。从天然海泡石、改性海泡石的结构与性质的比较上 ,对改性海泡石在废水治理、气体净化、土壤修复等污染治理方面的研究进展进行了评述 ,并对其开发利用进行了分析和探讨。

Modified sepiolite is a kind of fibriform clay mineral with abount of magnesium, it has the advantages of stronger adsorption,larager ion capacity for its special samdwich structure, causing less repollution,and can be reused,so it will be widely used in pollution control.The structures and characteristics of natural sepiolite and modified sepiolite are compared in this paper.The current situation of research and application in wastewater treatment,gases purification,soil remediation and so on are summarized.
