摘　　要：建立了气相色谱-质谱（GC/MS）法测定洗涤剂中乙醇胺类化合物分析方法。选用DB-624 MS分析柱,对目标物乙醇胺（MEA）、二乙醇胺（DEA）、二甲基乙醇胺（DMEA）和三乙醇胺（TEA）进行测定。方法线性相关系数为0.995~0.997;RSD值均小于4.9%;回收率为87.8%~117.9%。该方法可用于洗涤剂中乙醇胺类有机物的定性检测。This research provides an analytical method for the detection of ethanolamine derivatives in detergent by gas chromatography-mass spectrometry. The ethanolamine derivatives including monoethanolamine （MEA）, diethanolamine （DEA）, dimethylethano-lamine （DEMA） and triethanolamine （TEA） were separated by DB- 624 capillary column. The mass spectrometry was used to quantify the ethanolamine derivatives in detergent. Results showed that its relative standard deviation（RSD） was less than 4.9%, the correlation coefficients were from 0. 995 to 0. 997 and the recovery ranged from 87.8% to 117.9%. The results demonstrated that the method was featured with simple operation, good selectivity and high accuracy, and applicable in quanlitative determination of ethanolamine derivatives in detergent.
