Abstract

The reaction products of the photocatalytic oxidation of p-cresol were characterized by high performance liquid chromatography. The influence of p-cresol concentration as well as the presence of dioxygen and hydrogen peroxide on the rate of photocatalytic oxidation was studied. The p-cresol concentration in the irradiated systems was determined by spectrophotometric method using α-nitroso-β-naphtol or by the Principal Component Regression method (in the sample with hydrogen peroxide added). The reaction pathway of the photocatalytic oxidation of p-cresol in TiO₂ suspension was suggested.
