【Abstract】 A ferrocene modified green pepper seed carbon paste bioelectrode for the determination of ascorbic acid was described. The electrocatalytic behavior of the electrode was investigated. The electrode responded linearly to the ascorbic acid concentration in the range of 7.23 × 10-5 - 7.23 × 10-3 mol/L, response time was less than 10 s. The electrode has been used to determine the ascorbic acid in Vc tablet and the result was in good agreement with that of the pharmacopeia.更多还原
