It was found that good linear relationship between peak areas and concentrations of five nitro- benzene 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. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
