摘要
介绍了用催化消解密封法测定工业废水中化学需氧量的过程 ,与经典重铬酸钾法比较 ,此法缩短了消解时间 ,测定化学需氧量 (COD)值范围广 。
The essay introduces the way of determining the chemical oxygen demand of industrial waste water with catalysis resolution seal method.Compared with the way of the classics potassium double chromate.This way shorten the resolution's time,the value of determinimg the chemical oxygen demand is wide scale and it is much fit for determining surface water and high chlorine industrial waste water which is lower in the chemical oxygen demand.
