| Abstract: | TiO2 films were prepared by using sol-gel method,and phenol degradation test was conducted.The test results showed that the best conditions of TiO2 film preparation using sol-gel method were: tetrabueyl titanate∶ethanol∶distilled wate∶thick hydrochloric acid=1∶4∶0.25∶0.25,5-layer coating thickness,calcination temperature 500 ℃ and baking time 2 h.TiO2 films preparation under these conditions had high photocatalytic activity.Under the conditions of 30 W ultraviolet lights,phenol concentration of 50 mg/L,membrane area/solution volume of 8 cm2/L,continuous aeration,solution pH 4-6,and reaction time of 5 h,the degradation rate of phenol could reach 95%,and the performance of films was stable and could be reused.Preliminary research indicated that the degradation of this was first order reaction. |
