The effectiveness of peroxymonocarbonate () on the degradation of Reactive Blue 19 (RB19) textile dye was investigated in this study. The formation kinetics of produced in situ in a system was studied to control the experimental conditions for the investigation of RB19 degradation at mild conditions. The effects of metallic ion catalysts, the pH, the input and Co²⁺ concentrations, and UV irradiation were studied. The obtained result showed that Co²⁺ ion gave the highest efficiency on accelerating the rate of RB19 degradation by the H₂O₂– system. In the pH range of 7–10, the higher pH values resulted in faster dye degradation. The reaction orders of the RB19 degradation with respect to Co²⁺ and HCO₃^– were determined to be 1.2 and 1.7, respectively. The UV irradiation remarkably enhanced the radical formation in the oxidation system, which led to high degradation efficiencies. The COD, TOC removal, and HPLC results clearly revealed complete mineralization of RB19 by the system.

基于过碳一碳酸盐氧化系统的绿色工艺降解活性蓝19（RB19）

在本研究中，研究了过氧一碳酸盐（）对活性蓝19（RB19）纺织染料降解的有效性。的形成动力学产生原位在一个系统进行了研究，以控制RB19降解的在温和条件下进行调查的实验条件。研究了金属离子催化剂，pH，输入和Co ²⁺浓度以及UV辐射的影响。结果表明，Co ²⁺离子在H ₂ O _2-加速RB19​​降解速率方面的效率最高。系统。在7-10的pH范围内，较高的pH值导致染料降解更快。相对于对Co的RB19降解的反应级数²⁺和HCO ₃ ^-被确定为分别为1.2和1.7。紫外线辐射显着增强了氧化系统中的自由基形成，从而提高了降解效率。COD，TOC去除和HPLC结果清楚地表明该系统使RB19完全矿化。
