In situ studies of electrode regeneration by polishing during measurements
(English)Manuscript (preprint) (Other academic)
A general problem for all electronic tongues (and for most other sensor systems), especially when measuring in crude and complex media, is electrode fouling. The possibility of using a selfpolishing voltammetric electronic tongue has been investigated using cyclic voltammetry. The tested compounds were potassium hexacyanoferrat(II) (K4Fe(CN)6) and urea, respectively. Effects of short term drift, directly after polishing before the electrode is completely equilibrated, are repeatable.
