| Abstract: |
| A phase transfer catalyzed saponification pretreatment method for the determination of benzo（a）pyrene in edible oil by high performance liquid chromatography with FLD(HPLC-FLD) was established. The results showed that the detection limit of the method was 0.2 ng/mL, the quantification limit was 0.7 ng/mL, the average recovery was 96.15% - 103.2%, and the relative standard deviation was 2.61%-4.96%.The method had the advantages of reducing the consumption of organic solvents, reducing detection costs, simple operation, short detection time, etc., and met the requirements for rapid, convenient, accurate and sensitive detection of benzo(a)pyrene in edible oil. |
