Studies on Determination of Carbohydrate by Oxidation on Glassy Carbon Electrode in Basic Solutions

Abstract

Abstract: The determination of carbohydrate, such as glucose, fructose, maltose, lactose, sucrose, glycerol etc. was carried out with glassy carbon electrode by constant potential oxidation (0. 75 Vvs. SCE) or potential sweep oxidation(0. 2-0. 75 V) in 0.1 or 0. 2 mol/L NaOH solution. The lowest detection limit is 1 μg/mL, Abetter repeatability and long useful lifetime are obtained. The detection range of glucose is 0.1-5×10^-6mol/L. The response mechanism is discussed in this paper.

Key words: Electrochemical oxygen evolution, Electrochemical oxidation, Glassy carbon electrode, Glucose, Carbohydrate
