Abstract: Electrocatalytic oxidation of sulfhydryl compounds was effective on a copper hexacyanoferrate (CuHCF) film glassy carbon electrode, at a significantly reduced overpotential (0.55 to 0.65 V) and for a broader pH range (2.0 to 7.0). The electrocatalysis was evaluated in terms of several preliminary experimental parameters, such as buffer pH, surface adsorbent concentration, operating potential, mobile‐phase flow rate, and concentration dependence in batch and flow systems. Electrochemical liquid chromatography (LCEC) of sulfhydryl compounds gave a linearity over two orders of magnitude and detection limits at picomole level. Overlaying the CuHCF film electrode surface with a Nafion layer is essential for improving the catalysis stability and offers enhancement of the liquid chromatography electro chemistry (LCEC) response.
