【Abstract】 The photocatalytical degradation of tetracycline in TiO 2/ZnO suspension had been studied when sunlight or mercury lamp were used as light source.The effects of pH value,tetracycline initial concentration,light intensity,irradiated time,the proportion of ZnO and TiO 2,the volume of solution on the tetracycline degradation were discussed respectively.Photocatalytic efficiency of mercury lamp and sunlight were compared,the result showed sunlight is a promising lamp source.更多还原
