【摘要】 文中确定了在氯化钠-盐酸-氯化汞-钯(Ⅱ)体系富集时形成了Hg2Pd电活性互化物;验证了溶出催化波属于动力波性质,设计了平行于电极反应的化学反应模式,依此模型推导的近似的溶出催化电流is c p表达式与实验结果一致。

【Abstract】 In this paper, the following facts are described, during the electro-depositing of Pd(Ⅱ) with Hg(Ⅱ) on the glassy carbon electrode, an electro-active compound between metals, Hg2-Pd, was formed. When it was stripped, Pd showed a stripping process involved two electrons and two chrolide ions with irreversibility. The electrode with Hg2Pd was scanned in forward positive potential in a base-solution containing HClO4-HCl-SnCl2. The stripping catalytic pcak current obtained was related to the concentration of Sn(Ⅱ) and Cl-.
