Abstract

There is a never-ending search for new electrode materials for voltammetric or amperometric determination of various detrimental substances in drinking water. The basic requirements for new electrode materials are lower noise, broader potential range, mechanical robustness enabling measurements in flowing systems, compatibility with organic solvents making them compatible with high performance liquid chromatography (HPLC), flow injection analysis (FIA) or capillary electrophoresis (CE) with electrochemical detection (HPLC/ED, FIA/ED, CE/ED) and - last but not least - resistance towards passivation and electrode fouling which is probable the biggest complication in the practical applications of electroanalytical methods. One of the most promising non-traditional electrode materials is boron doped polycrystalline diamond film on a silica support, which is suitable for the determination of a wide spectrum of organic and inorganic analytes. The electrodes based on it possess excellent electrochemical properties, such as a low and stable background current over a wide potential range, corrosion resistance, high thermal conductivity and high current densities. Furthermore, this material offers superb micro structural stability at extreme cathodic and anodic potentials and resistance to fouling because of weak adsorption of polar species on the hydrogen terminated paraffin-like surface, which results in good responsiveness for many redox analytes without any pretreatment. Boron doped diamond film electrodes are applicable to voltammetric or amperometric determination of both oxidisable and reducible substances with limit of determination down to 10-8 mol L-1 without any preconcentration step. The chapter is devoted to their practical applications for both batch voltammetric analysis and continuous flow amperometric analysis (HPLC/ED, FIA/ED, CE/ED) of organic pollutants possibly present in drinking water.
