库仑分析以它特有的优点,已经发展成为电化学分析中的一个重要分支,广泛地应用于冶金、地质、环保、医学及化工生产中,而且已经出现了许多专著和评论,详尽地讨论了它的理论和实践的各个方面。这方面的研究仍在不断深入。例如新的终点指示方法的研究,电生滴定剂的途径,小电解池的设计及化学条件的改进和应用范围的扩大,均使库仑分析方法不断衍生一些新的技术,这些新技术具有更好的灵敏度、准确度和更快的分析速度。本文拟就库仑分析的一些新技术作一简单介绍。本文公式中所列均为通用符号。1.亚化学计量库仑法(A SubstoichiometricCoulometric Method of Analysis)除了惯常的库仑分析方法以外,这是使用最广的一种库仑分析法。该法由Атасян于1968年提出,是一种电流扰动技术。该法是将被测定离子的一小部分借恒电流沉积在固体或液体电极上,然后反向恒电流溶解之,在溶解过程中,记录工作电极电势对时间 Coulomb analysis, with its unique advantages, has developed into an important branch of electrochemical analysis and is widely used in metallurgy, geology, environmental protection, medicine and chemical production, and many monographs and commentary have appeared, which are discussed in detail All aspects of theory and practice. Research in this area is still in progress. Studies such as the new end-point method, the method of electrobio-titration, the design of a small electrolytic cell, the improvement of chemical conditions, and the expansion of the range of applications have led to the continuous derivation of new techniques by Coulometric methods that are better Sensitivity, accuracy and faster analysis. This article intends to make a brief introduction of some new technologies of Coulomb analysis. The formulas listed in this article are universal symbols. 1. A Substoichiometric Coulometric Method of Analysis This is the most widely used coulometric method, except for the usual coulometric methods. The law by Атасян in 1968, is a current disturbance technology. The method is a small part of the ions to be measured by constant current deposition on a solid or liquid electrode, and then reverse the constant current dissolved in the dissolution process, record the working electrode potential versus time
