| 摘 要： | 选用3种固体催化剂催化臭氧化降解磺基水杨酸.结果表明,MnO2和V2O5催化活性并不明显,而自制的钒氧化物(VO)催化剂具有较好的催化臭氧化性能.在本实验条件下与单独臭氧化相比,30min后VO/O3体系的COD和TOC去除率由原来的58%和25%提高到86%和61%.VO催化剂的作用机理是催化臭氧分解产生了高活性氧化剂(如羟基自由基等).

| Abstract: | Three kinds of solid catalysts were chosed for catalytic ozonation of sulfosalicylic acid (SSal). The results show that the catalytic activity of MnO2 and V2O5 is not clear while; that vanadium oxide (VO) prepared in lab has goodproperty of catalytic ozonation. Under lab conditions, compared with single ozonation COD and TOC removal rates ofVO/O3 enhance after 30min from 58% and 25% to 86% and 61%, respectly. The function mechanism of VO catalyst is catalytic decomposition of ozone to produce highly active oxidants (such as hydroxy radical etc.). |
