Title: Research on the method of nitrotoluene compounds in water determined by capillary gas chromatography
Abstract: The method of liquid-liquid extraction-capillary gas chromatography was established to determine p-nitrotoluene,2,6-dinitrotoluene,2,4-dinitrotoluene and 2,4,6-trinitrotoluene in the paper.In this method,the nitrotoluene-compounds were extracted by toluene from water,separated by capillary column,qualified and quantifed by gas chromatograph with electron capture detector.The results demonstrated that 4 nitrotoluene compounds can be separated completely with good linear correlation.The recoveries ranged from 90.2 % to 106.4%,and the accuracy RSD(n=5) ranged from 0.6% to 7.9% in this method.The method detection limits were from 0.007 to 0.053μg·L-1.The method was practical with advantages of simple operation and good accuracy.
