摘要
适用于工业循环冷却水化学需氧量测定的常用国标法有2种,分别为高锰酸钾法和重铬酸钾法。笔者对水质进行跟踪实验,分别对两种方法测出的数据进行分析与探讨,以筛选出更适用于工业循环水的测定方法。
CODCr and CODMn were two national standards in common use of the assay method for COD in industrial circulating cooling water.The experimental data of the two assay methods were analyzed and discussed in order to choose a better method for determination of industrial cooling water.
