利用唯物主义理论对铅在多晶金电极上的欠电位沉积行为研究及痕量铅电化学分析实验教学研究
Investigation of underpotential deposition behavior of lead on polycrystalline gold electrodes using materialist theory and its application in experimental teaching of trace lead electrochemical analysis
摘要
Abstract
This study employs underpotential deposition coupled with square wave voltammetry for the electroanalytical determination of trace lead in aqueous samples.The electrochemical phenomena are systematically interpreted through the lens of materialist theory,complemented by principles of physical chemistry and electrochemistry.The research examines the underpotential deposition process,two-dimensional phase formation,bulk deposition of lead,and concentration-dependent effects.Designed as a comprehensive analytical chemistry experiment,this approach demonstrates robust theoretical foundations and practical feasibility.The problem-oriented teaching methodology,integrated with materialist theory,significantly enhances the pedagogical effectiveness of experimental instruction.关键词
