快速消解全自动电位滴定法测量COD_(Cr)与传统方法的对比实验研究

The Comparison of Rapid Digested and Automatic Potentiometric Titration Method to Measure COD_(cr) with Traditional Method

文章介绍了用快速消解全自动电位滴定法、CODCr的传统消解标准滴定法在不同工业废水、河流和水库水样品中进行对比重复试验研究。根据试验结果分析得出:快速消解全自动电位滴定法检测CODCr可以代替实验室传统国家标准2小时消解滴定法,以更快的速度、更少的二次污染来测定水质CODCr。

The paper introduced a comparison about the result of rapid digestion and automatic potentiometric titration method, CODcr of 2 h digestion and traditional standard stitration at different industrial wastewater, river water and reservoir water samples. According to the test results, we reach a conclusion： rapid digestion and automatic potentiometric titration method to measure CODcr can replace the traditional national standards laboratory titration and 2 h digestion. The method was time-saving and less secondary pollution to the environment.
