| An analytical method has been developed for the determination of 15 phenols in water, using HPLC and both electrochemical and UV detection. The elution was carried out with the mobile phase 1 % aqueous acetic acid- acetonitrile (66 : 34). The preconcentration was achieved by liquid-liquid extraction. Performance of the LC system was checked. Linearity of the detector response and detection limit without concentration were determined. |
