Cyclic voltammogram (CV) and differential pulse voltammogram (DPV) of ferroceneboronic acid (FcBA), 1,1'-ferrocenediboronic acid (FcDBA), ferrocenecarboxylic acid (FcCA), 1,1'-ferrocenedicarboxylic acid (FcDCA), ferrocenylmethanol (FcM), and ferrocenylethanol (FcE) were recorded on a glassy carbon electrode in the presence of hypochlorite (ClO-) ion. The redox current of the ferrocene compounds in CV and DPV decreased with increasing the concentration of ClO- ion in μM level. The type of substituent in the ferrocene compounds significantly affected the electrochemical response to ClO- ion. Voltammetric and UV-visible absorption spectroscopic results suggested that the ferrocene compounds were oxidatively decomposed by ClO- ion. Thus, the ferrocene compounds can be used as redox marker for detecting ClO- ion in water.
