摘要
目的：建立胶粘剂中苯、甲苯、二甲苯、1,2二氯乙烷的毛细管气相色谱测定方法。方法：准确称取0.1～0.2 g鞋用胶粘剂样品,用二硫化碳溶解后毛细管气相色谱（FID）测定。结果：加标回收率在94.3%～101.1%,相对标准偏差均小于2%,检出限小于2.00 mg/L。结论：本法分离度好,灵敏度高,操作简便,适用于胶水中三苯及1,2二氯乙烷的测定。
Objective：To establish a method for the determination of benzene,toluene,dimethybenzene and dichloroethane in adhesive for shoes by capillary column chromatography.Methods：The procedure involved the disolving of 0.1～0.2 g exactly weighed sample by carbon bisulfide.Separation was achieved on capillary column,and then detected by flame ionization detector（FID）.Results：Recoveries were 94.3%～101.1%,the limits of detection and RSD for all chemicals were within 2.00 mg/L and 2%.Conclusion：The method is simple,effective,quick and easy to determine benzene,toluene,dimethybenzene and dichloroethane in adhesive for shoes.
