微量-乙胺示波极谱测定

Polarographic Determination of Micro Ethylamine

本文研究了碱性介质中一乙胺和对硝基苯胺重氮盐所形成偶氮化合物的极谱行为,并建立了微量一乙胺极谱测定方法。该法灵敏度高,对一乙胺的选择性好,可用于水、空气中微量一乙胺的直接测定,结果满意。

The polarographic behavior of a diazo compound prepared by ethylamine and p-nitro arene-diazonium salt in basic solvent was studied. We also established a polorographic method to de-termine micro ethylamine. This is a selective and sensitive method of the direct determination ofethylamine in water and air.
