摘　　要：利用气相色谱-质谱法,建立检测轻工产品（纺织品、皮革、竹木制品）中乙二醇单甲醚、乙二醇单乙醚、N,N-二甲基甲酰胺、乙二醇二乙醚、乙二醇乙醚乙酸酯、二乙二醇二甲醚、N-甲基吡咯烷酮和N-乙基吡咯烷酮这8种具有潜在生殖毒性的挥发性有机溶剂的简单方法。该方法采用30℃超声水浴提取,萃取溶剂为甲醇。在优化条件下,被测物的检出限在20-40μg/L,方法的回收率高于92.7%。Using gas chromatography-mass spectrometry （GC-MS）, a simple method is established to determine eight volatile organic solvents with potential reproductive toxicity in light industrial products （textiles, leathers, bamboo and wood products）. The eight solvents are ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, N, N-dimethyl formamide, ethylene glycol diethyl ether, glycol ether acetate, diethylene glycol dimethyl ether, N-methyl pyrrolidone and N-ethyl pyrrolidoney. Ultrasonic extraction at 30 ℃ is carried out with methanol as the extraction solvent. Under the optimal conditions, the quantification limits for the desired compounds are in range of 20-40 μg/L, the recoveries are more than 92.7%.
