The kinetics of the oxidative decolcourisation of crystal violet (CV+) as a cationic dye by peroxydisulphate using silver(I) catalyst in aqueous acidic medium has been studied. The effects of different parameters like hydrogen ion, silver(I), reactants concentration, micelles and temperatures are investigated. The reaction between [CV]+ and persulphate is investigated under pseudo-first-order kinetics by taking a large excess of [S2O8 2-] over [CV+]. The effect of surfactant micelles such as SDS and Triton X-100 on the reaction rate is investigated. The rate of reaction decreases with increasing [SDS] but had no effect with Triton X-100. Heat and entropy of activation and are calculated. An outer-sphere process for the electron transfer is the proposed mechanism for this reaction.

银 (I) 在水性和胶束介质中通过过硫酸盐催化结晶紫染料的氧化动力学

已经研究了使用银 (I) 催化剂在水性酸性介质中通过过二硫酸盐氧化脱色结晶紫 (CV+) 作为阳离子染料的动力学。研究了氢离子、银 (I)、反应物浓度、胶束和温度等不同参数的影响。[CV]+ 和过硫酸盐之间的反应在伪一级动力学下通过采用比 [CV+] 大量过量的 [S2O8 2-] 进行研究。研究了表面活性剂胶束如 SDS 和 Triton X-100 对反应速率的影响。反应速率随着 [SDS] 的增加而降低，但对 Triton X-100 没有影响。计算热和激活熵。电子转移的外球过程是该反应的建议机制。
