The degradation of resorcinol was carried out under uv-visible light by zinc oxide as photocatalyst. To measure the efficiency of the photocatalyst, the different variables studied included amount of photocatalyst, effect of oxidants peroxomonosulphate (PMS) and peroxodisulphate (PDS) on the photocatalytic oxidation of resorcinol on illumination ZnO surfaces has been investigated. The efficiencies of these oxidants on photocatalytic degradation of resorcinol are compared with that of PMS and PDS. The experimental results indicate that these oxidants exhibited enhanced rates of mineralization of resorcinol. A reaction mechanism, involving the generation of both hydroxyl radicals and sulphate radicals. In conclusion, this investigation indicated high potential of zinc oxide suspension to remove high level concentration of resorcinol under UV irradiation.
