[Method] Fe / C modified TiO2 photocatalyst was made by sol-gel and solvothermal synthesis methods. -octylphenol as test object, photocatalytic performance of the catalyst was investigated. Inluences of the Fe doping amount, catalyst amount, pH and sun-light irradiation on reaction were discussed. Moreover, catalyst performance under the condition of interfering ion existence was studied. [ Result] When Fe / C doping amount was 0.6% under the reaction condition of 25 ° C, pH = 9.0, 300 W mercury lamp and 1.0 g / L of catalyst amount, 4-t- L by degradation for 100 min. Rises of pH and light intensity could improve catalyst efficiency. The existences of Na +, K + and Ca2 + had no effect on degradation activity of the catalyst. [Conclusion] Fe / C modified TiO2 photocatalyst had better degradation effect on environmental hormone in the sewage.
