微波-活性炭联合作用在污染控制中的应用
Application of the combined effect of microwave and activated carbon in pollution control
-
摘要: 近年来,微波技术被越来越多地应用于污染控制方面的研究,其中相当一部分工作是借助于微波与活性炭的相互作用,即利用活性炭在微波辐照下可快速升温的特性,获得较高反应温度,同时活性炭还具有较强的还原能力和催化作用,从而达到分解吸附在活性炭孔隙内部或与活性炭共存于同一体系中的污染物的目的。首先从活性炭在微波场中升温的角度探讨了微波辐照对活性炭的作用,并就微波活性炭联合作用在气态污染物处理、液态污染物处理、土壤污染修复以及活性炭为载体的催化剂制备等方面的研究进展进行了评述。Abstract: In recent years, more and more investigations on the application of microwave technology in pollution control were reported, and many of them utilized the interaction between microwave and activated carbon. Since activated carbon is a very good microwave absorbing material, whose temperature rises very fast under microwave irradiation, and it is also an effective reductant and catalyst, pollutants adsorbed by or existing with activated carbon can be decomposed efficiently by microwave heating. This paper discussed the interaction of microwave and activated carbon from the point of carbon temperature rising in microwave field, and summarized the research progresses of the combined effect of microwave and activated carbon in the treatment of contaminated air, water and soil, along with in the preparation of carbonsupported catalyst.
