A reactive dye bath sample containing a mixture of dyes was ozonated and colour removal was obtained in a relatively short time of 30 min at 605 mgl-1 of ozone utilisation. The factors affecting ozonation were assessed by comparing the results of dye bath and synthetic samples. Results from dye bath and synthetic dye solution ozonation were found to be significantly different. NaCl and Na2CO3 were determined to have a slight effect only on the initial rate of ozonation. However, the effect of the chelating agent in terms of both time and ozone dose was significant and explained the differences between the results of the dye bath and dye solution ozonation.
对含有染料混合物的活性染料浴样品进行臭氧化处理，在臭氧利用率为605毫克/升的情况下，在相对较短的30分钟时间内实现了脱色。通过比较染料浴和合成样品的结果来评估影响臭氧化的因素。发现染料浴和合成染料溶液臭氧化的结果有显著差异。确定氯化钠和碳酸钠仅对臭氧化的初始速率有轻微影响。然而，螯合剂在时间和臭氧剂量方面的影响都很显著，这解释了染料浴和染料溶液臭氧化结果之间的差异。
