摘要
化学农药是一种危害高、难降解的环境污染物,农药残留对生态环境造成严重破坏并危害人体健康。光电催化具有安全环保、氧化能力强、易操作等优势,已成为降解农药残留最具前景的高级氧化技术之一。笔者综述了光电催化降解农药的基本原理、常用电极材料及制备方法,重点总结了光电催化降解农药的最新应用,评估了光源、pH等影响因素对农药降解的影响,这些为其短期内的实际应用提供了基础。目前涉及农药污水降解的研究较少,未来除针对电极材料改良外更应当侧重于实际农药废水的降解研究。
Pesticide is a kind of environmental pollutant with high hazards and difficult to degrade,and pesticide residues cause serious damage to the ecological environment and jeopardize human health.Photoelectrocatalysis has become one of the most promising advanced oxidation technologies for degrading pesticide residues due to its advantages of safety,environmental protection,strong oxidizing ability and easy operation.The basic principle of photoelectrocatalytic degradation of pesticides,commonly used electrode materials and preparation methods are reported in this study,with emphasis on summarizing the latest applications of photoelectrocatalytic degradation of pesticides.And the effects of light source,pH and other influencing factors on pesticide degradation are evaluated,which provide the basis for short-term practical applications.However,there are fewer research studies on actual pesticide wastewater degradation,and the degradation of actual pesticide wastewater in the future should be emphasized in addition to the electrode material improvement.
