Abstract:A method was established by high performance liquid chromatography determination of 15 polycyclic aromatic hydrocarbons in corn by 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 0.003 8 μg/kg to 0.079 μg/kg.The relative standard deviations of blank standard addition ranged was from 3.9% to 11.7%.The matrix spike recovery ranged was from 69.3% to 115.3%.The results of actual samples determination showed the method has good effect of separation and satisfis the demand of maize analysis.
Keywords:polycyclic aromatic hydrocarbon  acceleration solvent extraction  solid phase extraction  HPLC  maize crop
