分析化学所面临的问题仍是提高灵敏度、准确性、快速和自动化 ,电分析化学可直接进行电讯号的分离、放大和记录,无须讯号转换,故较其它方法更易于快速和自动化.本文提出在封闭式的流动体系微电解池进行伏安分析,并成功地用于矿石分析.目前,用这种电极,可进行四种类型的工作、即阴极伏安法、催化伏安法、循环伏安分析和阳极溶出伏安法.常规的阳极溶出法是用电磁搅拌,旋转工作电极,或是旋转电解杯以搅动试液来提高电解效率,这样不仅实验设备复杂且重现性较差.
Analytical chemistry is still facing the problem is to improve the sensitivity, accuracy, speed and automation, electro-chemical analysis of electrical signals can be directly separated, amplification and recording, no signal conversion, so easier and faster than other methods and automation.In this paper, Enclosed flow cell micro-electrolysis cells are voltammetrically analyzed and successfully used for ore analysis. Currently, four types of work are possible with this electrode, cathodic voltammetry, catalytic voltammetry, cyclic voltammetry Analysis and anodic stripping voltammetry.A conventional anodic stripping method is the use of electromagnetic stirring, rotating the working electrode, or rotating the cup to stir the test solution to improve the efficiency of electrolysis, so not only the experimental equipment is complex and poor reproducibility.
