The preparation of carbon paste electrodes (CPEs) modified with the hexacyanoferrate ion attached to synthetic hydrotalcite, a solid anion exchange resin Wofatit SBW and a liquid anion exchanger tris‐octylamine (TOA) used as pasting liquid, is described. Stability of the electrodes and their electrocatalytic properties were investigated. The surface‐modified hexacyanoferrate‐TOA‐CPE can be prepared and renewed in a simple and reproducible manner. The sensor was applied to the determination of ascorbic acid in real samples using a mediator accumulation/chronoamperometric detection scheme.
