Electrochemical Detection of Dissolved Ce in Water Using Boron-Doped Diamond Electrode

H Akrout, S Maximovitch

A comparative study of the electrochemical behavior and structural characteristics of boron-doped diamond electrode before and after working under high anodic potential conditions in aqueous acidic solution is performed. No changes can be detected on Mott-Schottky plots nor on micro-Raman images after a 500 hours working. The high stability of such a surface as probed by the structure-reactivity relationship is also revealed with the unmodified electrochemical response to the Ce³⁺/Ce⁴⁺ redox couple.
