摘　　要：采用全自动固相萃取处理废水,气相色谱-质谱联用法测定废水中的15种硝基苯类化合物,通过优化试验条件,使方法在0.100 mg/L~10.0 mg/L范围内线性良好。方法检出限为0.012μg/L~0.038μg/L,标准溶液11次测定结果的RSD为1.0%~7.5%。对实际水样做2个质量浓度水平的加标回收试验,平均加标回收率为78.0%~107%。Fifteen nitrobenzene compounds in wastewater were extracted by automatic solid phase and determined by gas chromatography-mass spectrometry(GC-MS).By optimizing the test conditions,the method had good linearity in the range of 0.100 mg/L to 10.0 mg/L.The method detection limits were from 0.012μg/L to 0.038μg/L.The RSDs of 11 measurements of standard solution were from 1.0%to 7.5%.The average spiked recoveries were from 78.0%to 107%when adding two mass concentration levels to practical samples.
