Determination of Nitrobenzene Compounds in Wastewater by Automatic Solid Phase Extraction-Gas Chromatography-Mass Spectrometry
Fifteen nitrobenzene compounds in wastewater were extracted by automatic solid phase and deter-mined 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 0.012 μg/L to 0.038 μg/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.
