摘　　要：以铂网栅电极作工作电极 ,设计制作了一种应用于紫外 可见光谱电化学研究的新型光透薄层电化学池 (OTTLE) ,并以铁氰化钾 亚铁氰化钾体系对此光谱电化学池进行了表征。铁氰化钾 亚铁氰化钾体系在该池中有良好的循环伏安特性 ,并可获得良好的紫外 可见光谱。测得的克式量电位E0 '。The design and construction of an optically transparent thin layer Pt minigrid electrochemical cell. are described. The cell consists of a Pt minigrid working electrode, an Ag/AgCl reference electrode and a Pt wire auxiliary electrode. Application of the cell is illustrated by thin layer cyclic voltammetry and ultraviolet-visible spectral-electrochemical data on K3Fe(CN)(6) system in aqueous 1 mol/L KCl supporting electrolyte. The value of the formal potential E-0 and the number of electron n of K3Fe(CN)(6) couple determined by ultraviolet-visible thin layer spectral-electrochemical. method are good agreement with those in literatures, which illustrates that the cell has fine spectral-electrochemical characteristics.
