Modification of electrodes with various metal hexacyanofenate films starting from the parent compound iron hexacyanoferrate (prussian blue) is a significant ongoing research activity in several laboratories globally. The promise for potential applications in various fields, such as electroanalysis, clectrocatalysis, electrochromism, electrochemical power sources and photoelectrochemical systems, has triggered lot of interest in the study of these compounds for surface modification. Moreover newer strategies are adopted in getting tailor-made surface films with improved electrochemical characteristics. One such approach has been the addition of surface-active agent during surface modification. Among the surfactants studied cationic surfactant cetyl trimethyl ammonium bromide (CTAB) has been found to influence the electrochemical properties of nickel hexacyanoferrate surface film greatly. Results of the cyclic voltammetric tudies carried out on these modified electrodes in the presence of various supporting electrolyte cations and their implications on surface modification are presented.
