分散蓝2BLN染料的二氧化氯氧化脱色研究

STUDY ON DECOLORIZATION OF DISPOSAL BLUE 2BLN BY CHLORINE DIOXIDE

我们用ClO2 氧化分散蓝 2BLN ,对其进行脱色 ,在 1分钟内脱色率为 90 %以上。在最佳条件下 ,研究了反应的动力学。用PMS半经验方法计算了 2BLN分子的键级。结果表明 ,脱色反应的级数 ,对 2BLN为 1级 ,对ClO2 为 0 .5级 ,这个反应是十分快的 ,开始于一个Sn2亲核历程。

We have treated Disposal Blue 2BLN with chlorine dioxide for decolorization.Under the optimum reaction condition,study of the dynamical mechanics of reaction with SF stop flowing spectrophotometer has been carried out.Utilizing the PM3 semi experience method to calculate the configuration of molecular of 2BLN,we have found out a theoretical reaction route,showing that the decolorization reaction order of 2BLN is 1,while that of ClO 2 is 0.5.This kind of reaction is considered as fast one,being a Sn2 path way.
