金电极上砷的假极谱法的初步研究

The Preliminary Studies of the Pseudo Polarography of Arsenic at a Gold Electrode

本文初步研究了金电极上砷的假极谱性质。所有假极谱图均使用BAS-100A电分析仪测量。实验结果与该体系的循环伏安图相一致,均符合拟可逆假极谱图理论。本文还简要讨论了pH对该假极谱图的影响。

In present paper the properties of the pseudo polarograms of Arsenic at a gold electrode are stud- ied. A BAS 100A Electrochemical Analyzer is used for all pseudo polarography measurements. The ex- periment results are consistent with the cyclic voltammograms of the system. Both results agree with the theories of quasi-reversible pseudo polarography. The effects of pH on the As pseudo polarogram at a gold electrode are briefly investigated.
