混合氧化法测定水中锰

ANALYSING Mn IN WATER WITH THE MIXTURE OXIDATION METHOD

本介绍了混合二种氧化剂,不经催化反应,无汞测定水中锰的方法。实验结果证明:该法具抗干扰力强,精密度高、准确度好、空白值低、简便快速、安全可靠的优点。作者认为,该法适应于基层单位水质卫生监测工作。

A new method of analysing Mn in water is introduced in this paper. In this method, used two kinds of oxidant, don't use Hg and needn't catalysis reaction. The result showed that it has the advantage of better antiinterference, better precision and accuracy, and lower reagert blank . The method is also rappidly and simple. The author considered it a good way to analyse Mn in water for primary level unit.
