摘要
化学耗氧量是水质监测的一个重要参数。对饮用水中化学耗氧量(COD)的通用测定方法进行了改进,采用一定功率的电炉直接加热试样,调节酸度后进行滴定,得到了和通用测定法相同的测定结果。
COD is one of the important parameters in water quality monitoring, a common method for determining COD in drinking water is improved. Sample is directly heated with an electrical stove and it is titrated after its acid content is adjusted, by which the result consisted with that of a common determining method is obtained.
