天然沸石在环保中的应用

天然沸石具有良好的离子交换性，吸附性及较好的催化性等性能，且资源丰富、价格低廉，在水处理、空气净化、放射性废物处理和抗菌剂的制备等环境保护与污染治理方面得到了广泛的应用。但目前我国天然沸石的开发利用总体水平还比较低，应加强各种天然沸石的成分，结构和性能研究，大力加强天然沸石的改型改性工艺技术研究，扩大天然沸石在环保中的应用范围。

APPLICATIONS OF NATURAL ZEOLITES TO ENVIRONMENTAL PROTECTION

This paper summarizes the results of recent work on the applications of natural zeolites to environmental protection. Because of the following properties of natural zeolites; excellent ion exchange, adsorption and catalytic activities, especially their availability and relatively low cost, natural zeolites have been widely applied in environment protection and waste treatment, such as wastewater treatment, air purification, radioactive waste disposal and antibacterial materials preparation. However, the level of exploitation of natural zeolites is relatively low in China. So the attention should be focused on the study of all sorts of natural zeolites and their composition, structure and property. And it should be reinforced to modify the structure and properties of natural zeolites in order to widen their application in environmental protection.
