摘　　要： Fenton试剂在降解有机污染物方面具有无二次污染等优势，但由于存在降解速率较慢的缺陷，在工程实践中尚未得以推广应用。考虑到微波具有促进有机化学反应速率的功能，采用微波和Fenton试剂联合作用氧化降解罗丹明B，对降解罗丹明B的优化实验条件进行了研究。首先研究了单一因素对降解效果的影响，然后对各种因素的综合作用效果进行了分析，得出了降解的优化实验条件。研究表明，微波能有效促进罗丹明B的降解脱色，而且能大大缩短反应时间，降低反应成本，增强Fenton氧化反应的活性，提高降解效果。 Fenton reagent is of some advantages such as un-pollution on oxidation degradation of organic contaminants. But this technique is not practical because the degradation speed is slow. Considering it is effective for microwave to accelerate organic chemistry reaction, mierowave-Fenton synergistic on oxidation degradation of Rhodamine B is investigated, and the optimum condition for Rhodamine B degradation is studied. At first, the function of single factor is studied. Then the effect is studied while all factors changes together, so the optimum condition is got. The results of experimental investigation show that microware can promote the degradation of Rhodamine B apparently,while time of reaction is greatly shortened and cost of reaction is evidently reduced. Microwave also enhances the activation of Fenton reagent to a great extent, and improves the effect of degradation.
