In this paper, the ability of three decolorization techniques including sonochemistry, electrochemistry and sonoelectrochemistry for decolorization of C.I Reactive Blue 49 in aqueous solutions have been compared. Various parameters affecting decolorization efficiency, such as pH, initial concentration of the dye, the decolorization time, H2O2 concentration and effect of applied potential on electrochemistry and sonoelectrochemistry, were evaluated. For further comparison, the methods were evaluated based on their ability in COD removal percentage. The maximum COD removal at the optimum condition of each method were 36.0%, 68.0%, 87.8% and 76.2% for sonochemistry, electrochemistry, sonoelectrochemistry with H2O2 and sonoelectrochemistry without H2O2, respectively. The result was an environment friendly method for removal of C.I Reactive Blue 49 from aqueous solutions.
本文比较了三种脱色技术，包括声化学、电化学和超声电化学，用于在水溶液中对 C.I 反应蓝 49 的脱色。评估了影响脱色效率的各种参数，如 pH 值、染料初始浓度、脱色时间、H2O2 浓度以及施加电势对电化学和超声电化学的影响。为了进一步比较，根据它们在 COD 去除率方面的能力对这些方法进行了评估。在每种方法的最佳条件下，最大 COD 去除率分别为声化学 36.0%、电化学 68.0%、有 H2O2 的超声电化学 87.8%和无 H2O2 的超声电化学 76.2%。该结果为从水溶液中去除 C.I 反应蓝 49 提供了一种环保的方法。
