  • 摘要: 为了提高有机物的臭氧化降解效率,工作中利用浸渍法制备了一种新型的三组分催化剂(记为V2O5-TiO2-AlF3/Al2O3)。催化臭氧化降解2,4-滴丙酸的实验结果表明,该催化剂能有效提高臭氧化的效率,体系可能遵循羟基自由基的作用机理。利用相对法计算结果表明,与单独臭氧化相比,V2O5-TiO2-AlF3/Al2O3催化臭氧化体系具有更大的Rct值。重复实验结果表明,该催化剂具有相对较好的稳定性。以上研究结果对推广催化臭氧化技术在实际废水处理中的应用具有重要的实际意义。
    Abstract: A novel tri-components catalyst characterized as V2O5-TiO2-AlF3/Al2O3 by XRD was prepared via incipient wetness impregnation to promote ozonation efficiency. The activity of the catalyst in ozonation was evaluated by degradation of 2-(2,4-dichlorophenoxy) propionic acid (2,4-DP). The results showed that the catalyst could greatly improve the efficiency of ozonation of 2,4-DP. The test of tert-butyl alcohol addition indicated that the catalytic ozonation of 2,4-DP might follow a hydroxyl radical-type mechanism. The Rct value of the catalytic ozonation calculated by the relative method was larger than that of ozonation alone. The repeated test indicated that the catalyst remained relatively stable in the catalytic ozonation of 2,4-DP. The above results are of great significance for extending application of catalytic ozonation of advanced oxidation process in wastewater treatment.
