法医毒物实践中五种除草剂光催化降解研究进展

Advances in the Photocatalytic Degradation of Five Herbicides in the Practice of Forensic Toxicology

在现代农业生产中除草剂扮演着重要角色,随着其用量和使用范围的不断扩大,除草剂造成的环境污染问题也随之而来.部分除草剂化学性质稳定,不易降解,在环境中长期蓄积会威胁人类健康和生态平衡.如何有效去除水环境中残留的除草剂成为当前人们关注的焦点.光催化技术因其高效、清洁、绿色等特点是降解除草剂的有效方法,但催化降解机理尚需进一步探讨,光催化性能尚需进一步提高.本文将重点对光催化降解法医毒物实践中五种除草剂的研究情况进行综述.

Herbicides play an important role in modern agricultural production,but the environmental pollution caused by herbicides also follows with the continuous expansion of its dosage and range of use.Some herbicides have stable chemical properties and are not easy to degrade.Long-term environmental accumulation will threaten human health and ecological balance.How to effectively remove residual herbicides in water environment has become the focus of current attention.Photocatalytic technology is an effective method to degrade herbicides because of its high efficiency,cleanness and green,but the mechanism of catalytic degradation needs to be further discussed and the photocatalytic performance needs to be further improved.In this paper,the review is focused on the research on photocatalytic degradation of herbicides in the practice of forensic toxicology.
