Determination of amide herbicides and metabolites in seawater
摘要
Abstract
A method was established for the determination of amide herbicides and their metabolites in seawater by gas chromatography-mass spectrometry(GC-MS).After filtration,the samples were passed through the HLB columns by automatic solid phase extraction,enriched and purified,then eluted with 3 mL n-hexane solution.Ion monitoring mode(SIM)was selected by gas chromatography-mass spectrometry to detect the eluent,and external standard method was used to quantify the target substance.The experimental results showed that good linearities for monoetha-nolamine(MEA),2,6-Diethylaniline(DEA),and metolachlor existed in the range of 1.0-25.0 μg/L with their detection limit and quantization limit were 6.0 ng/L and 12 ng/L.Alachlor,acetochlor,pretilachlor,butachlor have good linearities in the range of 2.0-50.0 μg/L with their detection limit and quantization limit were 12 ng/L and 30 ng/L.The relative standard deviations were between 5.3%-9.5%,and the recoveries were 68.7%-103.0%.The method is rapid,sensitive and can be used for the determination of amide herbicides and their metabolites in sea-water.[Chinese Fishery Quality and Standards,2024,14(5):01-06]关键词
