【摘要】本文研究了籍静电引力接着PtCl₄^2-/PtCl₆^2-的PVP修饰电极,采用动电势扫描法、旋转圆盘电极法和电位阶跃法等测定了不同H₂PtCl₆溶液浓度、PVP膜厚度和支持电解质条件下PtCl₄^2-/PtCl₆^2-体系的K_cx值。更多还原

【Abstract】 PtCl42-/PtCl62- may be incorporated in protonatcd PVP film. In this paper, we made the PtCl42- modified glassy carbon electrode, then evaluated the rate constant for self - exchange reaction - Kex. The effects to the Kex of the concentration of H,PtCl6 solution, the thickness of PVP film and the changes in nature of supporting electrolytes had also been studied.更多还原
