碱性高锰酸钾氧化测定水样中的总铬含量
Testing of Total Chromium in Water Sample by the Oxidation of KMnO4 in Alkaline Condition.
【摘要】 水样中的总铬通常采用酸性高锰酸钾氧化 ,二苯碳酰二肼 (DPC)分光光度法测定。在此原理基础上 ,通过实验研究了在碱性条件下的高锰酸钾氧化过程。结果证明该方法易于操作 ,准确度和精密度都理想
【Abstract】 Total chromium in water sample testedby acid KMnO 4, DPC Spectorphotometic titration.Based on this theory, the oxidation process of KMnO 4 in alkaline condition was studied. It was testified that this method was easy of operating,the accuracy and precision of the results were perfect.
