化学需氧量的快速测定方法研究

Rapid Detecting Method and Progress in Determination of Chemical Oxygen Demand

介绍了化学需氧量（ＣＯＤ）的快速测定方法及其进展，并从样品消解时间、试剂用量、准确度等方面对快速测定法与标准法进行了比较：同时提出了密封消解快速测定废水中ＣＯＤ的方法．

The different rapid detecting method and progress in determination of chemical oxy- gen demand were introduced in this paper, and the contrast of the rapid detecting method and stan- dard method was conducted. The method of rapid COD test by sealed-digestion was also studied.
