Abstract
Presents a method for analysis of five nitrobenzene compounds in water using solid phase extraction and gas chromatography-electron capture detector. It was found that good linear relationship between peak areas and concentrations of five nitrobenzene compounds holds in certain range. The average recoveries in samples were between 71.6%~87.8% with the relative standard deviations of 1.6%~9.3%. Detection limits of five nitrobenzene compounds were found to be 0.15 μg/L and 0.015 μg/L. The optimized method has been successfully applied to the analysis of surface water.
