Ozone oxidation for treatment of azo dye solution containing Remazol Black B was examined in the present study. Remazol Black B, as di-azo dye, was chosen owing to high solubility in the aquatic sources as pollutants. The effect of ozone reaction on the removal rate of color was investigated. UV–Vis spectroscopy was used to observe dye degradation. The laboratory-scale batch experiments were performed at constant 5 g/h ozone flow rate. The results with Remazol Black B synthetic dye solution designate that 94% color reduction was obtained at 25 min of ozonation. Buffering effect on the azo dye solutions was also evaluated, and the results of this study demonstrated for the removal of color and organic matters. Energy consumption of the treatment after ozone process was also estimated in this study.

在本研究中，研究了臭氧氧化处理含有 Remazol Black B 的偶氮染料溶液。选择 Remazol Black B 作为重偶氮染料是因为它在水生污染物中的溶解度很高。研究了臭氧反应对颜色去除率的影响。紫外-可见光谱用于观察染料降解。实验室规模的批量实验在恒定的 5 g/h 臭氧流速下进行。使用 Remazol Black B 合成染料溶液的结果表明，在臭氧化 25 分钟时获得了 94% 的颜色减少。还评估了对偶氮染料溶液的缓冲效果，该研究的结果证明了去除颜色和有机物。本研究还估算了臭氧处理后处理的能耗。
