Sf. Hou et al., THE ELECTROCHEMICAL-BEHAVIOR OF POLY-3,4- ELHYLENEDIOXY-THIOPHENE MODIFIED ELECTRODE AND THE ELECTROCATALYTIC OXIDATION OF ASCORBIC-ACID ONTHE ELECTRODE, Gaodeng xuexiao huaxue xuebao, 16(1), 1995, pp. 39-42
The electrochemical behavior of poly 3,4-ethylenedioxy-thiophene modif
ied electrode and the electrocatalytic oxidation of ascorbic acid (AH(
2)) on this electrode were investigated. The oxidation peak potential
shifts, negatively by 220 mV. The relationship between the oxidation p
eak current of ascorbic acid and its concentration in the rang of 1.0
X 10(-1)-1.0 X 10(-5) mol/L is linear. The modified electrode can be a
pplied to the determination of ascorbic acid in fruit and other biolog
ical samples.
