| 摘 要： | 臭氧和臭氧与其它工艺的结合使用对处理印染工业废水具有巨大的潜力.本文研究了臭氧与三种酸性染料在水中的反应动力学,并对染料——酸性媒介深黄GG与臭氧的反应过程进行了探讨研究结果表明:1.臭氧与染料在水中的反应遵循二级反应动力学.反应动力学常数受染料分子结构的强烈影响;2.臭氧与偶氮类染料在水中反应时,偶氮键(-N=N-)断裂,可能产生硝基和亚硝基化合物,这类化合物对人有很强的毒性,在工程实践中应有所警惕.

| Abstract: | The kinetics of acid dyes ozonization, as well as the reaction pathways, were studied experimentally. The results showed that:(1) The reactions were of second order. The rate constants were strongly affected by chemical structure of the dyes.(2) Certain toxic nitro-and nitraso-compounds might be formed during the ozonization due to the breakdown of azo bond. |
