FINE CHEMICALS 1003-5214 2023 40 6 article 水中微塑料光催化處理的進展 Advances in photocatalytic treatment of microplastics in water 近年來,微塑料(MPs)作為新型污染物引發的環境問題受到了廣泛關注,水體環境作為微塑料的主要匯集地其治理工作已成為熱點研究領域。微塑料具有穩定、易遷移、吸附其它污染物引發復合毒性等特性,傳統的水處理技術不能高效、徹底地將其去除。光催化技術在實驗室規模上可將MPs轉化為水溶性碳氫化合物和CO2,在徹底降解MPs方面表現出了巨大的潛力。本文綜述了光催化技術去除MPs的催化劑和催化機理及影響降解效果的主要因素,為去除水環境中MPs的研究提供可靠依據,并且針對復雜水環境中MPs光催化降解和催化劑的發展進行了展望。 In recent years, the environmental problems caused by microplastics (MPs) as new pollutants have received widespread attention. And the aqueous environment, which is the main pool of microplastics, has become a hot research area for its management. Due to their stability, ease of migration, and toxic effects caused by adsorption of other pollutants, etc., conventional water treatment technologies are not able to remove them efficiently and completely. However, photocatalysis can convert MPs to water-soluble hydrocarbons and CO2 at laboratory scale, showing great potential for complete degradation of MPs. This paper reviews the mechanism of MPs removal by photocatalysis and the main factors affecting catalysis to provide a reliable basis for the study of MPs removal in the aqueous environment. At the same time, it prospects the development trend of photocatalytic degradation of MPs and catalysts in complex aqueous environment. 水環境;微塑料;光催化;氧化降解 aqueous environment; microplastics; photocatalysis; oxidative degradation 鐘宛真,單斌,譚偉強,羅思義 ZHONG Wan-zhen,SHAN Bin,TAN Wei-qiang and LUO Si-yi 青島理工大學 環境與市政工程學院 1.School of Environmental and Municipal Engineering;2.Qingdao University of Technology;3.Qingdao 26600;4.Shandong jxhg/article/abstract/202210100922
