| 摘 要： | 按国标法对COD指标进行测定时,消解过程耗水、耗电量较大,对多批次的试样测定耗时较长,在科研、教学等方面的应用有诸多不便。用COD恒温加热器法进行消解水样,对葡萄糖、邻苯二甲酸氢钾两种标准溶液进行CODCr的平行测定,并对测定结果进行统计分析,得出用该法消解水样与国标法有可比性,无明显差异,而且在节水、节电、省时等方面优于国标法。

| Abstract: | It is not convenient for people to measure the COD of water samples according to the GB technique, because it consumes more quantities of water and electric power and especially needs more time in the determination of many batch samples. The paper adopts the COD constant temperature heating method to resolve water samples, conducts the CODcr parallel determination of two standard solutions, which is. the potassium phthalate standard solution and glucose standard solution and makes a statistic analysis of the empirical data The conclusion is that the two methods have a very good commensurability. |
