阳极溶出伏安法在铝、镁、硅、钛及其合金分析中的应用

APPLICATION OF ANODIC-STRIPPING VOLTAMMETRY IN ANALYSIS OF ALUMINIUM,MAGNESIUM,SILICON,TITANIUM AND THEIR ALLOYS

研究了汞膜电极阳极溶出伏安法的电化学机理及其简单的制作方法,并对常用的铂球镀银汞膜电极和旋转玻璃炭汞膜电极进行了比较.叙述了阳极溶出伏安法在铝、镁、硅、钛及其合金分析中的应用,以及各种样品中有关杂质元素的分析结果.

The electrochemical mechanism of a nodic-stripping voltammetry with the mercury film electrode and the simple preparation method of the electrode are studied.Comparison is made between the two conventional mercury film electrodes -the silver-plated platinum ball mercury film electrode and the rotating glassy car- bon mercury film electrode.The application of anodic-stripping voltammetry in ana- lysis of Al,Mg,Si,Ti and their alloys is presented and analysis results of related impurities in samples are listed.
