Existence of PAEs in water has already been a threat to the aquatic organisms and human health. This paper summarized the degradation of PAEs by photocatalytic oxidation technology: the effects of PAEs on the removal efficiency by such factors as irradiation time, irradiation intensity, catalyst dosage, initial concentration of PAEs, pH value of reaction solution and additives; the reaction dynamics of PAEs decomposition; and the degradation pathway of PAEs. At last, the furthe
