摘　　要：采用气相色谱-质谱法测定纺织品中对氯苯胺的含量,研究了对氯苯胺溶液的储存稳定性,结果表明对氯苯胺标准溶液和样品溶液在低温(小于5℃)、高浓度(例如30 mg·L-1)下的储存稳定性好。在最佳的分析条件下,进行了全毛精纺花呢样品的加标回收试验,加标水平为10.0,20.0,30.0 mg·kg-1,回收率分别为86.0%,100.6%,97.6%,相对标准偏差(n=6)小于9.0%。GC-MS was applied to the determination of p-chloroaniline in textiles.Stability of p-chloroaniline solution was studied and it was found that the standard solution and sample solution were stable at high concentrations（e.g.,30 mg·L-1） and low temperatures（e.g.,5 ℃）.Under the optimized conditions,tests for recovery and precision were made by standard addition method at 3 different concentration levels of 10.0,20.0,30.0 mg·kg-1,values of recovery found were 86.0%,100.6% and 97.6% respectively,and values of RSD′s（n=6） was less than 9.0%.
