测定化学需氧量(COD)的影响因素及改进方法

The Influence Factor and Improvement Methods of Mensurating COD

在综述还原性物质、空白实验值、水样保存和均化等对COD测定影响及解决办法的基础上,着重探讨各种还原性物质消除方法和原理,最终优化了还原性物质的消除方法。

The influence factor of mensurating COD, such as the reduction material, blank experiment value, preservation and average of water sample were summarized in this paper. On the basis of those, the elimination methods and principle of various kinds of reduction material were discussed and optimized.
