摘要
以太阳光、汞灯为光源 ,Ti O2 / Zn O复合半导体为催化剂光催化处理四环素溶液 ,探讨了催化剂的配比、溶液体积、光照时间、p H、初始浓度、光强等 6种因素对光催化活性的影响 ,比较了汞灯和太阳光作光源时的光催化效果 ,结果表明 。
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.
