摘要
阐述了水中高锰酸盐指数的概念 ,由化学反应机理论述了化学需氧量与高锰酸盐指数之间的关系 ,由 1 998年淮河流域安徽段全年监测数据拟合出相关函数 ,并对实测工作中高锰酸盐指数出现的异常情况进行调查研究 ,提出了高锰酸盐指数测定操作方法的改进意见 ,对实际监测工作有一定参考价值 .
The conception of COD Mn in water and the chemical reaction mechanism relationship between COD cr and COD Mn are discussed in this peper.A relevant function is drawn up from the whole year mitoring data of 1998 in Huai River basin in Anhui.Investigations are carried out about abnormal phenomence in daily COD Mn analysing.A improved idea about COD Mn 's analysing methed is raised in the paper.it would have some value to actual monitoring work.
