Abstract

Abstract: The electrochemical behaviour of SnO₂ electrode modified with L-B films of ferrocenederivative (FcOCOC₁₇H₃₅) has been studied in Fe(CN)₆^3-/4- solution.By measuring theelectrochemical kinetic parameters i.e.rate constant of electrode reaction K_s, the chargetransfer mediation of modified molecules at SnO₂/Fe(CN)₆^3-/4- interface was analyzed.Decrease in K_s for SnO₂ electrode modified with mono- or multi-layers of ferrocenederivative L-B film indicated that faster electron transfer is expected only in such amodified molecule which can act as a fast charge transfer mediator at SnO₂/Fe (CN)₆^3-/4- interface.

Key words: L-B film, chemical modified electrode, ferrocene derivative
