拟除虫菊酯农药的微波辅助无极汞灯下的降解机理研究
Study on Photodegradation Mechanism of Synthetic Pyrethroids under Microwave-Assisted Eletrodeless Discharge Mercury Lamp
摘要
Abstract
The study applied microwave-assisted electrodeless discharge mercury lamp （MW-EDML）, to degrade γ-cyhalothrin （ γ-CY）, fenpropathrin （FP） and cypemethim （CP） in aqueous solution. The degradation products were enriched by solid phase extraction （SPE） and then identified by gas chromatography-mass spectrometry （GC-MS）. According to identification of six kinds of degradation products, the degradation mechanism of SPs was studied, which include five possible pathways： hydrolysis of ester bonds, hydrolysis of ct-cyano group, decarboxylation, breaking of ether bonds, oxidation, hydroxylation of benzene ring and reaction with solvent. The result showed that MW-EDML is a effective and simple tool for degradation of pyrethreids （SPs） and could be applicable to degrade other organic pollutants in aqueous solution.关键词
