石墨电极阳极溶出伏安法中,产生不正确的结果的主要原因之一是在电极上沉积的组分之间的相互作用。在电解过程中,元素间这种相互作用的结果是形成固溶体、金属间化合物或化学化合物。现代阳极溶出伏安法(a.s.v.)中电化学生成的最简单的二元体系可以分为以下的主要类型。第一,体系中组分之间在电极表面上彼此完全不发生作用。形成这种类型的二元的或更复杂的体系的元素,包括周期表第Ⅱ族 d 区元素(Zn、Cd、Hg),第Ⅲ族和第Ⅳ族p 区元素(In、Tl、Sn、Pb)以及铋。这些元素可按 Graphite Electrode One of the major causes of incorrect results in anodic stripping voltammetry is the interaction between the components deposited on the electrode. The result of this interaction between the elements during electrolysis is the formation of solid solutions, intermetallic compounds or chemical compounds. The simplest binary systems electrochemically generated in modern anodic stripping voltammetry (a.s.v.) can be divided into the following major types. First, there is absolutely no interaction between the components in the system on the electrode surface. Elements that form a binary or more complex system of this type include elements of Group II d-zone (Zn, Cd, Hg), Group III and Group IV p-zone elements (In, Tl, Sn, Pb) and bismuth. These elements can be pressed
