Electroanalytical study of Prussian Blue modified glassy carbon paste electrodes

摘要: Two types of glassy carbon (GC) powder (i.e., Sigradur K and G) have been mixed with mineral oil to obtain paste electrodes (GCPE's). The electrochemical behavior such at different percentages has evaluated respect the electrochemistry ferricyanide as revealed cyclic voltammetry best composition was chosen. GC then modified Prussian Blue (PB), unmodified a fixed amount in order PB (PB-GCPE's). PB-GCPE's (PB-GC) were compared dependence on their performances by studying parameters current peak, Ep, anodic cathodic ratio, charge density) amperometric response H2O2. Data interpretation based surface area is presented. GCPE's selected PB-GC tested H2O2 probes all analytical together pH evaluated. Some preliminary experiments these assembled glucose, lysine lactate biosensors are also reported. (Less)
