摘要
采用气相色谱-质谱联用法测定纺织品中的硝基苯类化合物,通过正交试验优化前处理条件,研究了最佳的气相色谱-质谱分析条件。该方法在0.5~20.0 mg/L范围内线性关系良好,相关系数R^(2)>0.995,在不同贴衬样品中的平均回收率为90.6%~96.6%,精密度(RSD)为1.3%~6.6%,方法的检出限(LOD)为0.05~0.08 mg/kg,方法的定量限(LOQ)为0.15~0.26 mg/kg。该方法前处理简便,检测效率高,精密度好,能满足纺织品中硝基苯类化合物的测定需求。
Nitrobenzene compounds in textiles are determined by gas chromatography-mass spectrometry(GCMS)method.The pretreatment conditions are optimized by orthogonal test,and the optimal GC-MS analysis conditions are studied.The linear range of the method is 0.5~20.0 mg/L,and the correlation coefficient R^(2) is over 0.995.The average recoveries are 90.6%~96.6%,RSD is 1.3%~6.6%,LOD is 0.05~0.08 mg/kg,and LOQ is 0.15~0.26 mg/kg.The method has the advantages of simple pretreatment,high detection efficiency and good precision,which can meet the needs of determination of nitrobenzene compounds in textiles.
