Determination of dinitrobenzene and nitrochlorobenzene in surface water by GC-MS
A method for the analysis of dinitrobenzene and nitrochlorobenzene in surface water was established by purging and trapping combined with gas chromatography tandem mass spectrometry.The linear relationship of dinitrobenzene and nitrochlorobenzene in water was good in the concentration range of 2.00～80.0μg·L-1.The detection limits were 0.01～0.03μg·L-1.The recoveries were 88.4%～104.0%with relative standard deviations(n=6)less than 5%.This method is simple,sensitive,accurate and reliable,and can meet the requirements for the analysis of dinitrobenzene and nitrochlorobenzene in surface water.
