摘要
该文综述了近年来发展迅速的真空紫外技术(VUV)在有机污染物降解中的应用。VUV降解污染物的作用机理通常包括直接光解和基于活性基团的氧化作用,且基于自由基的高级氧化通常在污染物降解中占主导作用。此外,该文介绍了VUV体系降解污染物的效能及动力学模型,总结了该体系降解污染物主要的影响因素,并综述了真空紫外技术的优缺点。之后,作者点明了制约该技术发展的主要问题,展望了真空紫外技术的发展前景。
The recently rapid development of vacuum ultraviolet(VUV)technology in the degradation of organic pollutants has been comprehensively reviewed.The degradation of pollutants by VUV is usually due to the direct-photolysis and the formed reactive species,and the advanced oxidation process based on the formed radicals is usually primary reason for the removal of organic pollutants.The degradation efficiency of organic pollutants and the related kinetic models using VUV system are illustrated,and the dominant influencing factors are summarized.Additionally,the advantages and disadvantages of VUV were evaluated.In the end,the possible limitation and future development of VUV in treating organic pollutants were also discussed.
