摘　　要：目的:建立液相色谱串联质谱法测定生活饮用水中10种苯基尿素类杀虫剂。方法:水样经0.45μm过滤膜过滤后进样,用超高压液相色谱-三重四极杆串联质谱进行分析测定。结果:10种苯基尿素类杀虫剂能较好地分离,峰面积与其浓度均具有良好的线性;10种物质的回收率在93.2%～109%之间,相对标准偏差(RSD)小于6.44%。结论:该方法灵敏度高、特异性好,线性关系及重现性好,适合对生活饮用水中10种苯基尿素类杀虫剂定性定量分析。Objective ：To establish liquid chromatography tandem mass spectrometry method for the determination of 10 kinds of phenyl urea insecticides in the drinking water. Methods： Water samples were injected after filtration through 0.45 μm membrane, then analyzed by ultra - high pressure liquid chromatography - triple quadrupole tandem mass spectrometry. Results： The components of 10 kinds of phenyl urea insecticides can be well separated, the peak area and concentration has good linearity; the average recoveries were between 93.2% to 109%, relative standard deviation （RSD） was less than 6.44%. Conclusion： The method had high sensitivity, specificity, lineari- ty and repeatability, which was suitable for qualitative and quantitative analysis of 10 kinds of phenyl urea insecticides in drinking water.
