支持電解質(Supporting Electrolyte) 是電化學體系中為維持溶液導電性和控制離子強度而添加的高濃度惰性電解質。它本身不參與目标電極反應,但為電化學反應提供必要的離子環境和導電通路,确保實驗結果的穩定性和可重複性。其核心作用與構成如下:
增強溶液導電性
通過高濃度離子(如K⁺、Cl⁻)降低溶液電阻,減少因歐姆壓降(IR Drop)導緻的電位偏差,使施加于工作電極的電位更精确,提升電化學測量(如循環伏安法)的準确性。
控制離子強度與雙電層結構
恒定離子強度可屏蔽帶電粒子間的庫侖相互作用,穩定擴散層厚度,避免電場分布不均對電極反應動力學的幹擾。例如在電分析化學中,維持離子強度能确保擴散電流與待測物濃度的線性關系。
最小化遷移電流影響
高濃度惰性電解質大幅降低待測物離子的遷移貢獻(遷移電流),使擴散成為物質傳輸的主要機制,簡化數據分析模型(如依據Cottrell方程計算擴散系數)。
通過上述機制,支持電解質成為電化學實驗設計的基石,确保反應在可控的電場環境下進行,為科學研究與工業應用提供可靠數據支撐。
supporting electrolyte(支持電解質) 是電化學領域中的一個專業術語,主要功能是輔助電解過程的進行。以下是詳細解釋:
