Here we introduce the structuring of boron doped diamond (BDD) electrodes using a self-organised mask and reactive ion etching (RIE) in oxygen plasma for electrochemical measurements of selected metal ions. The samples were analysed by SEM, Raman and X-ray photoelectron spectroscopy. The electrochemical performance of structured BDD was compared to as-grown BDD and standard glassy carbon (GC) electrodes employing standard cyclic voltammetry and differential pulse anodic stripping voltammetry. Separate and simultaneous detection of Cd2+- and Pb2+ ions is discussed in relation to the electrode morphology and content of graphitic phase. To determine trace amounts of metal ions we evaluated the repeatability of measurements, which is statistically expressed as the relative standard deviation (RSD) of consecutive determinations.
