建立了一种分析污水污泥样品中目前使用的有机磷农药及其代谢物的宽极性范围的方法。采用不同溶剂的超声辅助提取法（UAE）进行提取。采用液相色谱-串联质谱法（LC-MS/MS）在正离子或负离子模式下电喷雾电离（ESI）测定污泥中OPs的水平。以含1%乙酸的乙腈为萃取剂，加样回收率为83.2% ~ 106.4%，RSD最佳
A method has been developed for the analysis of a wide polarity range of the currently used organophosphorus pesticides (OPs) and their metabolites in sewage Sludge samples. Extraction was carried Out using ultrasonic assisted extraction (UAE) with different solvents. The levels of OPs in sludge were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) using electrospray ionization (ESI) in positive or negative ion mode. Extraction with acetonitrile containing 1% acetic acid gave the best results with recoveries between 83.2% and 106.4% and RSD
