建立了纺织品中1-甲基-2-吡咯烷酮的检测方法。采用超声波辅助丙酮对样品进行萃取,萃取温度为40℃,时间为40 min,萃取液经聚四氟乙烯滤膜过滤后,用气相色谱串联质谱法(GC-MS)进行测定。当标样的质量浓度为0.5~10 mg/L时,线性相关系数≥0.999,检出限0.1 mg/kg,空白样品的加标回收率≥80%。 A method for the determination of 1-methyl-2-pyrrolidone in textiles was established. The sample was extracted with acetone and the extraction temperature was 40 ℃ for 40 min. The extract was filtered through a Teflon filter and determined by GC-MS. When the standard concentration of 0.5 ~ 10 mg / L, the linear correlation coefficient ≥0.999, the detection limit of 0.1 mg / kg, the spiked sample recovery ≥ 80%.
