| 中文摘要: |
| 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0.100mg/L～10.0mg/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%。 |
| 英文摘要: |
| 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 0.100mg/L to 10.0mg/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. |
