摘要
建立了同时定量测定腈纶布料及其服装中的苯、甲苯和二甲基甲酰胺残留的毛细管气相色谱分析方法。测得的回收率分别为 93 .3 % ,1 0 1 .8% ,94.9% ;变异系数为 3 .4% ,2 .0 % ,2 .8%。方法简便、快速、准确。
A simple method for the analysis of residual benzene, toluene and N,N-dimethyl formamide (DMF) in acrylic fabrics by wide-bore capillary gas chromatography is presented. The sample was extracted by carbon disulfide (CS\-2) for an hour. The results showed that this is a rapid and sensitive method with less interferences and fairly good precision. The detection limits were 0.1, 0.1 and 2.0 ng for benzene, toluene and DMF respectively. The recoveries were 93.3%\|101.8% and coefficients of variation were 2.0%\|3.4%.
