[Objective]The research aimed to study synthesis of the TiO2 photocatalyst modified by Fe/C and photodegradation of 4-t-octylphenol.[Method]Fe/C modified TiO2 photocatalyst was made by sol-gel and solvothermal synthesis methods.4-t-octylphenol as test object,photocatalytic performance of the catalyst was investigated.Influences 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 ℃,pH =9.0,300 W mercury lamp and 1.0 g/L of catalyst amount,4-t-octylphenol concentration decreased from 1.00 to 0.02 mg/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. 展开更多
