水中敌草隆去除技术研究进展

Progress of Diuron Degradation in Water

近年来水体中除草剂污染问题越来越严重,敌草隆是目前应用广泛的化学除草剂之一,其施用后在水中的残留对人类健康产生了极大威胁。文章综述了各种敌草隆处理技术,包括吸附法、电Fenton法、超声化学法、光催化法、电化学法,以及微生物法降解敌草隆的效果、影响因素,同时阐述了这些处理技术降解敌草隆过程中降解产物和可能的降解机理,提出了今后在水中敌草隆处理方面应该进一步研究的问题。

Recent years, the problem of herbicide has deteriorated seriously. Diuron is one of the widely used herbicides which remains in water after its insufflation and causes a great threat to human health. This article reviews the various pro-cesses of diuron degradation including adsorption, electrochemical Fenton, ultrasonic chemical method, photocatalytic and electrochemical method, microbial degradation method; also expounds the degradation byproducts and potential degradation mechanism of all these processes. The issues on diuron degradation that should be further studied in future are put forward.
