摘要
试验证明，ＣＯＤ光度测定法是可行的，本法测定范围为０～２００ｍｇ／Ｌ，测定波长为４３４ｎｍ，Ｋ２Ｃｒ２Ｏ７标准溶液最佳使用浓度为００６７５ｍｏｌ／Ｌ（１／６Ｋ２Ｃｒ２Ｏ７），在此浓度下，ＣＯＤ为２００ｍｇ／Ｌ的葡萄糖溶液实际测得值只比标准滴定法低１８％。
This paper compared two methods for analytzing atmospheric SO 2. One method is colorimetry published in 'Environmental technical norms', the other is spetrophotometry published in 'Manual of Atmospheric and Exhaust Gas Monitoring'. The determination results obtained by these two methods were some what different. The former's results were slightly higher than those of the later.
