摘要
酸性高锰盐滴定法和哈希DR3900分光光度法分别对水中CODMN分别进行检测。用哈希DR3900分光光度计测定,操作简便,但在实际应用中还存在一些技术问题。从样品浓度的选取对其分析性进行了探讨。结果证明,哈希DR3900分光光度法可以得到较准确的分析结果,但是测定值偏低,对于高浓度水样尚需进一步探讨其改进方法。
Respectively for CODMN in water were respectively detected by acidic permanganate titration and Hashi DR3900 spectrophoto-metric method. Using the hash DR3900 spectrophotometer is simple operation, but some problems existing in practical application. This article from the selected sample concentration on the analysis were discussed. Results show that, the Hash DR3900 spectropho-tometry can be analyzed more accurate results, but the measured value was lower, for high concentration sample still need to be further explored the improve method.
