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 。
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.
