摘要
选用催化快速分光光度法测定水中ＣＯＤ，是目前国内在微量分析测定方法中较先进的分析方法，优点是仪器、设备简便，操作简单，分析快速，成本低，节省大量化学试剂，方法的空白值较好，精密度较高，测定的标准偏差为１．４，回收率达９５％以上．
The method to detect COD by cataltsis rapid spectrophotometry is introduced in the paper.It's a more advanced way in the micro-analysis mathod in our country.The advantages are the equipment easily to operate,analysis rapidly as well as lots of regents can be saved.The black value of this method is better.The accurate degree in experiment is high.It's standard devistion is 1.4.The recovery percent is above 95%.
