An analytical method has been developed for the determination of 15 ph
enols in water using HPLC and both electrochemical and UV detection. T
he elution was carried out with the mobile phase 1 % aqueous acetic ac
id-acetonitrile (66:34). The preconcentration was achieved by liquid-l
iquid extraction. Performance of the LC system was checked linearity o
f the detector response and detection limit without concentration were
determined.
