液相色谱串联质谱法快速测定水中敌百虫等6种农药
Fast Determination of 6 Pesticides(Such as Trichlorfon)in Water by LC-MS/MS
摘要
Abstract
With the implementation of the Standards of Drinking Water Quality(GB 5749-2022),more and more pesticides have been included in drinking water quality monitoring which haven't efficient detection methods.Thus,a fast detection method including 6 pesticides(trichlorfon,thiophanate-methyl,simetryne,metalaxyl,isoprothiolane and trifluralin)was established.Samples were detected bydirect injection-high performance liquid chromatography-tandem mass spectrometryafter being filtered by PTFE membrane.Detection limits of this method were ranged from 0.02 μg/L to 3.1 μg/L.The method recoveries were 60.5%~120.3%in pure water,69.3%~129.8%in drinking water and 75.1%~127.2%in surface water.Relative standard deviation were 0.5%~6.2%in pure water,0.4%~7.5%in drinking water and 0.5%~5.1%in surface water.Four differentfilter membranes were tested on the effect of method recoveriesand the PTFE membrane was selected.The method can well applied in routine and emergency detectionof drinking water and surface water with high efficiency and reliability.关键词
