Electrocatalytic determination of thiols using hybrid copper cobalt hexacyanoferrate modified glassy carbon electrode

•A Cu/Co hybrid hexacyanoferrate (HCF) was electrosynthesized on GC electrodes.•The preparation of the CME was rapid, inexpensive and simple to carry out.•Three thiols l-cysteine, l-glutathione, 1,4-btanedithiol were analyzed by the CME.•To limit the fouling of the CME, the CMEs were thermally treat...
