Determination of Benzo[j]Fluoranthracene in Solid Waste by Accelerated Solvent Extraction with Liquid Chromatography UV Detecto
Leberteco Flex-HPSE fast solvent extractor(ASE),Thermo Field UltiMate3000 liquid chromatograph.A method was developed for the determination of benzo[j]fluoranthrene in solid waste by pressurized fluid extraction and liquid chromatography with ultraviolet detector.The rapid solvent extracter was extracted for 5 min at 1400 psi and the extraction agent was a mixed solution of dichloromethane and n-hexane(1∶1).The extraction was repeated for three times.The CNWBOND Si silica gel SPE column was used as the purification column,and the steps of activation,sample loading,leaching,elution and solvent replacement were carried out.The linear range of benzo[j]fluoranthrene was 2.00～10.0 mg/L,r=0.999,the detection limit was 0.02 mg/kg,and the detection limit was 0.08 mg/kg.The relative standard deviations of benzo[j]fluoranthrene at 4 pg,6 pg and 8 pg gradient levels were 4.1％～5.9％,and the recoveries were 89.0％～97.4％.
