| Abstract: | Objective To develop a method to determine trace Benzo（a） pyrene in water. Methods The method of high performance liquid chromatography with fluorescence detection was adopted, a Waters PAH C18 （250 mm ×4. 6 mm× 5 mm） was used as analytic column and the flow rate of mobile phase, methanol was 1.2 ml/min. The analyte was enriched by ENVI - 18 cartridge and eluted with tetrahydrofuran. Results The detection limit of method was 0. 002 mg/L and the correlation coefficient was 0. 999 9. The average rate of recovery was 86.4% and RSD was 2. 33% （ n = 6 ） . Conclusion The method is simple, accurate and reliable for the determination of Benzo（a） pyrene in water. |
