| Abstract: | A C18 stationary phase was synthesized for a custom-made HPLC column. When compared to a commercial C18 column, better chromatographic performances were obtained. This column was successfully applied for simultaneous determination of p,p′-DDT, o,p′-DDT, benzo(a)anthracene, benzo(b)fluoranthene, and benzo(a)pyrene in waters by high performance liquid chromatography coupled with dual detectors (diode array and fluorescence detectors) combined with solid phase extraction. Low method detection limits were obtained, i.e., p,p′-DDT: 0.5 µg L?1, o,p′-DDT: 1 µg L?1, benzo(a)anthracene: 2.5 ng L?1, benzo(b)fluoranthene: 5 ng L?1, and benzo(a)pyrene: 2.5 ng L?1. High recoveries that ranged from 82 to 94% were obtained for all compounds. |
