摘要: 本文研究了两种常用阳离子染料—半菁类的阳离子桃红FG和二氮半菁类的阳离子艳蓝RL在水溶液和染色废水中的O3氧化特性。实验结果表明:脱色率可达99%以上;就脱色而言,在水溶液中的臭氧氧化指数分别为2.67和2.85,其废水的CODCr去除率与废水水质有关,CODCr去除率范围为15～40%。Abstract: This paper studies the ozonization characteristics of two categories of cation dyes-the cation peach-colour FG and the cation beauty-blue RL.Experimental results show that the decolorizing efficiency for the wastewater containing these dyts reached 99%.In the aqueous solutions,the ozonization indexes for decolouring are 2.67 and 2.85 respectively.The CODcr removal was found to be related with the quality of waste water, and the removal rate ranged from 15-40%,
