伏安法在镀液分析中的应用 Title: Application of Voltammetric Techniques in Electroplating Solution Analysis Introduction: Voltammetry is awidely used technique in electrochemical analysis that measures the current flowing through an electrode as afunction of the applied potential. The method offers several advantages, including high sensitivity, selectivity, and the ability to investigate various electrochemical processes. This paper will highlight the applications of the voltammetric method, particularly the voltammetric stripping techniques, in the analysis of electroplating solutions. 1. Electroplating Process: Electroplating is acommon industrial process used to coat metallic objects with athin layer of another metal. This method provides functional and aesthetic benefits, such as increased corrosion resistance, improved conductivity, and decorative finishes. However, maintaining the quality of the plating solution is crucial for achieving desired plating results. Monitoring and controlling the solution composition is necessary to prevent defects, improve longevity, and reduce waste generation. 2. Voltammetric Techniques in Electroplating Solution Analysis: 2.1. Cyclic Voltammetry (CV): Cyclic voltammetry is aversatile technique used to determine the redox behavior and electrochemical characteristics of species in a solution. In the context of electroplating solution analysis, CV can provide valuable information about the species involved in plating reactions, identify impurities, and understand the extent of side reactions. By measuring the peak potentials and peak currents, parameters such as deposition potential, deposition current, and plating efficiency can be determined. 2.2. Stripping Voltammetry Techniques: Stripping voltammetry includes various techniques like anodic stripping voltammetry (ASV) and cathodic stripping voltammetry (CSV). These methods are particularly useful for determining the concentration of metal ions in electroplating solutions.
