摘要

微波结合活性炭的微波敏化方式可大幅提高Fenton试剂氧化能力

为研究产物的生成路径及微波、活性炭、H2O2之间的关联性

自制不同孔隙材料及不同Fe含量的碳材料

采用多组对照实验验证产物O2、CO、NO2的可能生成路径及微波、活性炭的作用

最终得到微波敏化下的芬顿试剂催化氧化NO的反应机理. 结果表明:采用活性炭加微波的敏化方式后

NO脱除效率可从33.1%提高至46.3%

O2生成量从6.9%增加到18.6%

同时伴随着体积分数68×10-6的CO生成；O2可通过活性炭的吸附作用及Fe2+的催化作用产生；C及NO只能被芬顿反应过程中生成的·OH、HO2·氧化成CO及NO2；微波可强化体系内所有可发生反应

活性炭能进一步提高微波敏化的前提是发达的孔隙

同时活性炭中存在的部分Fe元素参与到了芬顿反应.

Abstract

Microwave sensitization including microwave and activated carbon can significantly improve Fenton oxidation ability. To study the generation mechanism of product and the relationship between microwave

AC and H2O2

materials of different sizes and different Fe content were made

several control experiment were carried out to prove the possible generation ways of O2

CO2 NO23 and the effect of microwave and AC

the mechanism of NO catalytic oxidation by Fenton reagent combined with microwave sensitization were obtained at last. The results indicate that the microwave sensitization can increase the NO removal efficiency from 33.1% to 46.3%

increase O2 content from 6.9% to 18.6%

and produce 68×10-6 CO. O2 generates through AC's absorption and catalysis of Fe2+. C and NO can only be oxidized into CO and NO2 by the OH

HO2 produced by Fenton reaction. Microwave can intensify all possible reactions in the reagent

the developed pore structure is prerequisite of microwave sensitization of AC

and part of the Fe included in AC joins in the Fenton reagent.
