| Abstract: | A method was established by high effective liquid chromatography determination of 16 polycyclic aromatic hydrocarbons in soil samples with accelerated solvent extraction purify coupled with solid-phase extraction cleanup after detective condition was optimized. The linear relations between absorption value and each polycyclic aromatic hydrocarbon mass concentration were good, and detection limits ranged from 0. 412 ng/g to 3. 974 ng/g. The relative standard deviations of blank standard addition ranged from 1.2% to 12.7%. The matrix spike recovery ranged from 60.4% to 126%. The results of actual samples determination show the method has good effect of separation and meets the demand of soil analysis. |
