摘　　要：采用气相色谱法对10种不同的塑料复合食品包装袋中可能残留的溶剂如甲苯、二甲苯（邻、间、对）、丙酮、乙醇、乙酸乙酯、丁酮、正丁醇、乙酸丁酯进行分析。方法采用HP-5色谱柱分离，氢火焰离子检测器FID检测，结果显示10种溶剂分离效果好，线性相关性高，样品加标回收率中苯系物介于78％-80％，其他溶剂介于86％-94％，最低检出限可达0．003mg／m^2。The residual solvent such as methylbenzene, dimethylbenzene, acetone, alcohol, acetic ether, butanone, nbutyl alcohol, butyl acetate in 10 kinds food packaging materials were determined by gas chromatography. HP -5 chromatographic column and FID detector was used in the method. As a result, 10 kinds of solvents were separated very well, and linear correlation was very high. Recoveries of samples as benzene were 78% - 80% and the others were 86% - 94%. The minimum detection limit was 0. 003 mg/mg^2.
