A voltammetric comparison of the properties of carbon paste electrodes containing glassy carbon microparticles of various sizes

Popis výsledku v původním jazyce

This paper deals with comparison of carbon paste electrodes (CPEs) prepared from different sized microparticles of glassy carbon powder and mineral oil for their use in direct current voltammetry (DCV), differential pulse voltammetry (DPV) and cyclic voltammetry. Carbon pastes contained 250 mg of spherical microparticles of glassy carbon with a diameter of 0.4-12 mu m, 10-20 mu m, 20-50 mu m or crystalline graphite with average diameter of particles 2 mu m and mineral oil as a binding liquid. The electrochemical properties of CPEs were studied using potassium ferrocyanide in aqueous supporting electrolytes and 5-amino-6-nitroquinoline (5A6NQ) in mixed methanol-water supporting electrolytes. All tested electrochemical characteristics at these electrodeswere compared with the performance of a solid glassy carbon electrode. The results show that when the size of glassy carbon spherical microparticles is increasing the CPE electrode passivates more easily by 5A6NQ and obtained limits of d
