Abstract: A method was developed for the determination of nitrobenzenes?compound in soil by GC-MS with accelerated solvent extraction. Method of drug samples for nitrobenzenes?compound by acetone and n-hexane(1:1) extraction,solid-phase extraction separation,drying and concentrating,analysis by GC-MS with ASE,internal standard method for the quantitative analysis.The results were present as follows.The method was suitable for the determination of nitrobenzenes?compound using the acetone and n-hexane(1:1) as elution solvent in soil.It had good separation effect and the calibration curves showed good linear relationship. The correlation coefficients >0.995. Samples extracted showed the highest recovery. The recoveries of nitrobenzenes?compound were in range of 71.6%~119% and the relative standard deviations were 0.2%~1.1%. The detection limits were 0.05~1.31μg/kg.The method had merits of simplicity,accuracy,sensitivity and it can meet the test requirements of nitrobenzenes?compound in soil.
