摘要
有机农药一般光稳定性好,属生物难降解性有机物,在使用中易对周围生物种群及人类的健康带来危害.农药污染逐渐受到人们的关注,农药降解也成为研究的热点课题之一.利用高级氧化技术中的光催化方法降解有机农药是近年来兴起的一门绿色及高效新技术.本文从有机农药降解处理意义,有机农药分类和基本特性及常规处理方法等几个方面,综述了TiO2、类Fenton方法为主的高级氧化技术对有机农药光催化降解的基本原理,概述了其光催化降解机理和降解产物毒理研究现状,并展望了有机农药光催化降解研究趋势.
Organic pesticides, which were of light-stablity and non-biodegradation. The contamination of pesticides has gained widely attention for threat to human health and biological population. The photodegradation of organic pesticides, applied in recent years, was a green and efficient technology of advanced oxidation technology. In this paper, it was mainly summarized the basic principles of advanced oxidation technology using TiO2, Fenton-like photocatalystic systems from the aspects of organic pesticides degradation, the classification of organic pesticides and conventional processing methods. The photodegradation mechanism of organic pesticides and the survey of the toxicology of degradation products are overviewed. Moreover, it was previewed the research tendency of photodegradation of organic pesticides.
