Electrochemical oxidation and electroanalytical determination of xylitol at a boron-doped diamond electrode

Xylitol undergoes two oxidation steps in an irreversible diffusion-controlled process. The oxidation process P1 is mediated by the
- OH generated at the BDD hydrogen-terminated surface and a maximum peak current was obtained at a pH of 7.0, and the electroanalytical method developed, (employing square wave voltammetry) yielded low detection (1.3×10-6 mol L-1), and quantification (4.5×10-6 mol L-1) limits.
