摘　　要：本文采用气相色谱-质谱联用法,对鼓粉盒中6种塑化剂进行测定,并优化萃取时间和萃取溶剂。当其质量浓度在(0.08~80.0)mg/L范围内时,与色谱峰面积呈良好的线性关系,相关系数r^(2)均大于0.9991,检出限为(3.2~10.5)mg/kg,定量限为(10.7~35.2)mg/kg;3个加标水平下回收率88.5%~101.3%,测定结果的相对标准偏差1.9%~5.8%(n=6)。结果表明:该方法灵敏度高、操作简便、定量准确,适用于鼓粉盒中塑化剂的分析测定。In this paper,6 plasticizers in drum cartridge were determined by gas chromatography-mass spectrometry,and the extraction time and solvent were optimized.When the mass concentration of plasticizer was in the range of(0.08~80.0)mg/L,there was a good linear relationship with the chromatographic peak area,the correlation coefficients r^(2) were greater than 0.9991,the detection limits were(3.2~10.5)mg/kg,and the quantitation limits were(10.7~35.2)mg/kg.The recoveries were 88.5%~101.3%at the three spiked levels,and the relative standard deviations were 1.9%~5.8%(n=6).The results show that the method has high sensitivity,simple operation and accurate quantification,and is suitable for the analysis and determination of plasticizer in drum cartridge.
