摘要：

建立了固相萃取、毛细柱气相色谱-质谱、内标标准曲线法使用选择离子（SIM）监测采集数据定量分析水中N-甲基吡咯烷酮（NMP）的分析方法。试验结果表明，当添加N-甲基吡咯烷酮质量浓度为1～10 mg/L时，待测试样中N-甲基吡咯烷酮的回收率达82.5%，相对标准偏差RSD（n=5）小于5%，其最低检出限为0.05 mg/L，方法操作简单、快速、准确、灵敏度高、重现性好，可用于水和废水中N-甲基吡咯烷酮残留量的分析。

Abstract:

A method for the determination of N-methyl-2-pyrrolidinone(NMP) in water and wastewater by solidphase extraction(SPE),capillary gas chromatography-mass spectrometry and calibration curve method containing an internal correction standard has been established. The results show that when the mass concentration of NMP added is 1-10 mg/L,the recovery rate of NMP in the sample to be tested reaches 82.5%,the relative standard deviations (n=5) is lower than 5%,and the lowest detection limits is 0.05 mg/L. The method is simple,rapid,accurate and efficient,and has high sensitivity and good repeatability. It could be used in residue analysis of NMP in water and wastewater.

Key words: N-methyl-2-pyrrolidinone(NMP), GC-MS, wastewater
