  Kinetics of oxidation of indigo carmine by N-sodio-N-bromotoluenesulfonamide in acidic buffer medium

  摘要：

  The kinetics of oxidation of indigo carmine (IC) by N-sodio-N-bromotoluenesulfonamide or bromamine-T (BAT) in pH 5 buffer medium has been investigated at 30 degrees C using spectrophotometry at 610 nm. The reaction rate shows dependencies of first-order on [IC](0), second-order on [BAT](0) fractional order on [H+], and inverse first-order on [p-toluenesulfonamide]. The addition of chloride and bromide ions, and the variation of ionic strength of the medium have no influence on the reaction rate. There is a negative effect of the dielectric constant of the solvent. Activation parameters have been calculated. A single-pathway mechanism for the reaction, consistent with the kinetic data, has been proposed. (C) 1997 John Wiley & Sons, Inc.

  dye by oxidation process using chloramine-T as oxidant and Co(II) as catalyst in acidic buffer media, pH 5.8 has been kinetically studied at 300 K. Decolorization of indigo caramine dye was followed spectrophotometrically. Decolorization and oxidation led to a decrease in Chemical Oxygen Demand of the dye. The Co(II)-catalyzed reaction shows first-order dependence of the rate on chloramine-T and indigo

  在300 K酸性缓冲液中，以氯胺-T为氧化剂，Co（II）为催化剂，通过氧化工艺对靛蓝胭脂红染料进行脱色。用分光光度法对靛蓝胭脂红染料的脱色进行了动力学研究。脱色和氧化导致染料的化学需氧量降低。Co（II）催化的反应表明速率对氯胺T和靛蓝胺浓度的一阶依赖性。它还显示了对[Co（II）]和[H +]。卤离子或氯胺-T甲苯磺酰胺的还原产物的添加以及介质的离子强度和介电常数的变化对反应速率没有显着影响。激活参数从Arrhenius图进行评估，并提出了反应机理。
