Na-bentonite and TiO2 were used as raw materials to prepare composite photocatalytic materials,which were characterized by SEM and XRD,and then applied to the fenton-uv co-catalytic system to remove polycyclic aromatic hydrocarbon (PAHs) in water.Orthogonal experiments were carried out on the basis of studying the influence of single factors such as catalyst dosage,agitation mode and fenton dosage.The results showed that the removal rate of PAHs in the collaborative catalytic system was higher than that of ordinary TiO2.At room temperature,when magnetic stirring and ultraviolet irradiation were applied for 3h,the adding amount of TiO2/bentonite was 1.8g,and when fenton was added 30mL,the removal effect of PAHs was up to 94%.
