Abstract
Electrochemical properties of nickel on a gold disk electrode from aqueous hexagonal lyotropic liquid crystalline phase in Brij 78 as supporting electrolyte through the electrochemical techniques of cyclic voltammetry (CV) and convolution-de-convolution voltammetry, coupled with method of digital simulation was investigated. Scan rate effect on the peak height and on the peak position was indicated. It was found that scanning the potential in the cathodic direction produced two peaks, corresponding to the reduction of Ni2+ to Ni metal. Also reversing the potential to the anodic direction was characterized by nickel dissolution.
