Abstract

Abstract: In this paper,the procedure of preparation of Cu-PTFE composite electrode by electroplating was investigated and the electroanalytical properties of alcohol, aldhyde and carbohydrate on Cu-PTFE composite electrode were examined.The results from experiments indicated that the detection limit by constant potential amperometry with Cu-PTFE composite electrode in flow injection analysis was lower(3×10^-6mol/Lfor glucose) and the process of electrode was electrocatalytic oxidation by Cu₂O₃.

Key words: Composite electrode, Constant potential amperometry, Flow injection analysis
