改性活性炭在环境保护中的应用

Modified Activated Carbon and Its Application in Environmental Protection

活性炭是一种应用广泛的吸附催化剂 ,其性能取决于它的孔隙结构和表面化学性质。为了提高其吸附效率和改善其吸附选择性及其催化性能 ,往往需要对活性炭的孔隙结构进行调整以及改变其表面化学性质。综述了活性炭的改性方法及其特点。

Activated carbon (AC) is one of the widely used materials as catalyst and adsorbent. It has been known that there is a positive correlation between its porosity and capability, and that porosity structure and surface chemical properties are essential. In order to improve its properties, such as adsorption efficiency, adsorption selectivity and catalysis, it is important to adjust the porosity and change the surface chemical property. In this paper, some modified methods and the uses of the modified AC in pollution control are reviewed.
