Introduction
The moisture determination via the
coulometric Karl Fischer titration
belongs to one of the most common titrations [1,2].The main advantage of this type of Karl Fischer titration is the simple handling,the rapid titration and the accuracy of the results.New reagents omitting pyridine have improved accuracy and safety of the titration.Yet,another disadvan-
tage is to overcome.Common commercial reagents contain
halogenated hydrocarbons,mostly carbon tetrachloride in the catholyte and chloroform in the anolyte.They are undesired with regard to environmental contamination,human toxicity and biodegradation.But,omitting these compounds changes the chemical character and behaviour of the reagents.The "water capacity" of the reagents drops to about one third of the usual capacity and the reagents titrate much more slowly.The reason for this electrochemical behaviour is not known.The role which the halogenated hydrocarbons play during the titration has recently been reported in two earlier publications [3,4].We decided to investigate the function of the halogenated hydrocarbons in the coulometric Karl Fischer titration.This paper reports on our investigation of the reaction in the cathode compartment.

属于最常见的滴定[1,2]之一.这种类型的卡尔费休滴定法的主要优点是操作简单,快速滴定和结果的准确性.省略吡啶的新试剂滴定的准确性和安全性得到改善.然而,另一个缺点
踏歌是要克服.普通的商业试剂含有
阴极和阳极液中氯仿卤化烃,大多四氯化碳.他们是不受欢迎的关于环境的污染,人类的毒性和生物降解.但是,忽略这些化合物改变试剂的化学性质和行为.“试剂”水能力下降到通常的容量约三分之一和试剂滴定速度要慢得多.这个电化学行为的原因尚不清楚.卤代烃滴定过程中发挥的作用,近日有报道称,前两个出版物[3,4].我们决定调查的卡尔费休库仑滴定卤化烃的功能.本文对我们的反应在阴极室的调查报告.
