| Abstract: | Using self-constructed electrochemical detection system for HPCE, o-diphenol, o-cresol, phenol and p-diphenol were simultaneous determined with amperometric detection. With a 25 μm×70 cm fused-silica capillary, the optimum conditions for separation and detection of four phenols are 0.01 mol/L K2HPO4( pH 11) running electrolyte, 20kV separation voltage, hydrodynamic injection 15 s at 20 cm height, and +0.85V (vs. SCE )detection potential. The method was successfully applied to determine phenols in laboratory waste water. |
