Electrochemical properties of PrBaCo2O6 electrode in the oxidation of glucose and methyle orange

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