摘要
分别采用重铬酸钾法与氧化微回流法测定相同条件下邻苯二甲酸氢钾标准溶液的COD值,对比两种方法的测试结果表明,氧化微回流法操作简便,结果准确,与国标法不存在显著性差异。
The COD values of potassium hydrogen phthalate standard solutions were measured respectively in the same condition by potassium dichromate method and oxidation micro-reflux method. The experimental results showed that oxidation micro-reflux method had the advantages of convenient operation and high accuracy. There was no significant difference between these two methods.
