微波降解硝基苯水溶液的研究

Study on Degradation of Nitrobenzene in Aqueous Solution by Microwave

目的:硝基苯类化合物是常用的有机化学工业原料,但是,若进入水体,将成为有毒有害的污染物。硝基苯性质稳定,属难降解有机物,不易被生物降解,对环境的危害很大。本课题刨去传统的处理方法,采用新的微波技术降解硝基苯的方法,为此类废水的处理工程寻找一种经济,环保,便捷的方法。方法:本课题采用静态实验,以硝基苯为研究对象,选择微波功率为操作参数,在硝基苯降解过程中,一定时间取样,并且采用紫外分光光度计进行检验硝基苯的浓度,计算硝基苯降解率。为微波降解效果提供可靠的实验数据。研究微波降解硝基苯水溶液的可行性和规律性。结果:实验证明:微波对硝基苯水溶液的照射,确实有降解作用,并且降解效果良好。结论:微波降解硝基苯水溶液的可能性很大,且规律性良好。

Objective：Nitrobenzene organic compounds are commonly used industrial raw materials, however, if access to water,will be toxic and harmful pollutants. Nitrobenzene stable ,refractory organic matter is not easily biodegradable,the environment great harm. Nitrate to the subject of traditional treatment planing, using a new method of microwave degradation of nitrobenzene,wastewater treatment works for such an economical, environmentally friendly and convenient way. Methods： The subject of static experiments to nitrobenzene as the research object,select the operating parameters of microwave power in the nitrobenzene degradation process, a certain time sampling, and tested by UV spectrophotometer concentration of nitrobenzene, nitro calculated benzene degradation rate. Degradation effect for the microwave to provide reliable experimental data. Study the feasibility of microwave nitrobenzene and regularity. Results： Experimental results show： Microwave irradiation of nitrobenzene in aqueous solution, does have degradation, and degradation of good. Conclusion： Microwave nitrobenzene great poasibility, and good regularity.
