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.
