摘要： 称取一定量湿巾样品加乙醇超声提取后,离心过滤,采用气相色谱法检测湿巾中的丙二醇含量,外标法定量。结果表明:该法在2.50～200.00 mg/L质量浓度范围内线性关系良好,1,2-丙二醇的相关系数为0.998 9,检测限为1.50 mg/L,RSDA=2.32%,加标回收率为92.10%～97.20%;1,3-丙二醇的相关系数为0.999 4,检测限为2.00 mg/L,RSDA=3.15%,加标回收率为93.40%～97.25%。该方法前处理简便快捷,精密度、准确度、稳定性好,检测结果准确可靠。

Abstract: A weighted sample of wet wipe was extracted by ethanol under assistance of ultrasonic wave,and the extract was filtered via centrifugation.Then the filtrate was detected by gas chromatography to determine the content of propylene glycol in wet wipes.The quantification was identified with external standard method.Results showed that the method exhibits good linearity in the mass concentration range of 2.50-200.00 mg/L.For 1,2-propylene glycol,the correlation coefficient is 0.998 9,detection limit is 1.50 mg/L,RSDA=2.32%,and spiked recovery is 92.10%-97.20%.For 1,3-propylene glycol,the correlation coefficient is 0.999 4,detection limit is 2.00 mg/L,RSDA=3.15%,and spiked recovery is 93.40%-97.25%.

Key words: wet wipes, propylene glycol, gas chromatography
