摘　　要：建立了气相色谱-质谱联用法测定染整助剂中硫酸二甲酯的分析方法，考查了不同萃取方法、温度、萃取时间、色谱柱、溶剂、质谱条件等因素对试验的影响，优化了方法，使得DMS的检出限达到1mg／kg，加标回收率达到78．8％～102．9％，相对标准偏差为4．5％。8．6％。该方法简单、灵敏、准确，可用于柔软剂、防水剂、氨基硅油等染整助剂样品的测定。Determination methods of dimethyl sulfate from dyeing and finishing additives based on gas chromatography- mass spectrometry was developed. The influences of different extraction methods, temperature, time, chromatographic column, solvent and mass spectrometry condition on experiment system were investigated. By the optimization, the detectable limit of DMS reached to 1 mg/kg, and the recovery of standard addition was 78.8%-102.9%, and the relative standard deviation was 4.5%-8.6%. This method was simple, sensitive and accurate. It could be used in detecting dyeing and finishing additives, such as softer, waterproofing agent, amino silicone oil, and so on.
