支持电解质(Supporting Electrolyte) 是电化学体系中为维持溶液导电性和控制离子强度而添加的高浓度惰性电解质。它本身不参与目标电极反应,但为电化学反应提供必要的离子环境和导电通路,确保实验结果的稳定性和可重复性。其核心作用与构成如下:
增强溶液导电性
通过高浓度离子(如K⁺、Cl⁻)降低溶液电阻,减少因欧姆压降(IR Drop)导致的电位偏差,使施加于工作电极的电位更精确,提升电化学测量(如循环伏安法)的准确性。
控制离子强度与双电层结构
恒定离子强度可屏蔽带电粒子间的库仑相互作用,稳定扩散层厚度,避免电场分布不均对电极反应动力学的干扰。例如在电分析化学中,维持离子强度能确保扩散电流与待测物浓度的线性关系。
最小化迁移电流影响
高浓度惰性电解质大幅降低待测物离子的迁移贡献(迁移电流),使扩散成为物质传输的主要机制,简化数据分析模型(如依据Cottrell方程计算扩散系数)。
通过上述机制,支持电解质成为电化学实验设计的基石,确保反应在可控的电场环境下进行,为科学研究与工业应用提供可靠数据支撑。
supporting electrolyte(支持电解质) 是电化学领域中的一个专业术语,主要功能是辅助电解过程的进行。以下是详细解释:
