Voltammetric studies of oxidation of p-cresol at boron doped diamond electrode

Abstract

Cresols are toxic environmental pollutants. In this contribution possibilities of quantitation of p-cresol at BDD electrodes with different boron concentration are presented.

Well shaped anodic voltammetric peakswere obtained for both, anodically pre-treated semi-conductive 500 ppm and 1000 ppm, and metallic-type 4000 ppm and 8000 ppm BDD electrodes in acidic media. Limits of detection for DP and DC voltammetry are lower than 0.1 mu mol l(-1) for the preferred boron doped diamond film deposited at B/Cratio 4000 ppm.
