摘要：

Ascorbic acid (AA) is a vital component in the diet of humans and is known to take part in several biological reactions. The investigation and determination of AA has therefore always been of interest for chemists. There is a higher overpotential for the bare electrode, because the product of AA oxidized is a surface fouling to the electrode. There are some electrocatalytic oxidation and determination of AA at the chemically modified electrode (CME). In this paper,we describe the improved voltammetric behavior of AA and its determination at a polyalanine CME.
