库仑—新极谱电分析法测定铝合金中的锌

Determination of Zn in Al Alloy by Coulometric-New Polarographic Electroanalysis

本文提出以Bi—EDTA作发生试剂,汞膜电极为发生电报,采用库仑法与新极谱法相结合的方法测定铝合金中的锌。对几种标准样进行测定,结果满意。

In this paper an electro-analytical methad based on coulombmetric titration associated with neopolarographic method; using Bi-EDTA as generating reagent and mercury membrance electrode as generating electrode is proposed for the determination of zinc in aluminium alloy. Results obtained with several standard samples are satisfactory.
