摘要/Abstract

摘要： 利用欠电位沉积和方波伏安法相结合对水样中微量铅进行电分析研究，利用唯物主义理论、物理化学及电化学理论知识对电化学实验现象进行阐述。利用铅在多晶金电极上的欠电位沉积与方波伏安法相结合对水体样品中痕量铅进行分析研究的综合实验课程具有理论性强、可操作性强的特点，以问题导向性模式教学及唯物主义理论提升实验教学效果。

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.

Key words: Dialectical materialism, Lead, Underpotential deposition, Polycrystalline gold electrode, Electroanalysis
