| Popis: | In this work, we investigate the possibility of using double cobaltite with the composition PrBaCo2O6 as an electrocatalyst in the oxidation of organic compounds. A screen-printed carbon electrode modified with the PrBaCo2O6 drop method was investigated as a sensor for glucose. The amperometric signal of this sensor is logarithmically dependent on the analyte concentration according to the equation: I (μA) = 9.485⋅ln(C (mM)) + 17.864 (R = 0.9951). The limit of detection is 0.52 μM (at S/N = 3). The linearity range is 0.0-17.5 mM, which corresponds to the physiological values of blood glucose concentration (3.3-5.5 mM). In addition, the possibility of electrooxidation of a refractory organic compound (methylene orange) using a modified electrode was shown. © Published under licence by IOP Publishing Ltd.
