Abstract: Hollow Fe2O3 particles were prepared by hydrothermal synthesis. The effects of Fe2O3 concentration, initial concentration of dioctyl phthalate (DOP), pH value and H2O2 concentration on the photocatalytic degradation of DOP aqueous solution were experimentally studied using halogen lamp as light source. The photocatalytic degradation mechanism of DOP with Fe2O3 particles was studied with GC-MS technology. The results showed that without H2O2 addition, the photocatalytic degradation rate of DOP is the greatest when the Fe2O3 concentration, DOP initial concentration, and pH value were 100mg/L, 20mg/L and 7, respectively. During the degradation process, the branched chain of benzene ring degrades first, then the benzene ring is opened, and the ultimate products are CO2 and H2O.
