| Remarks： |
The preparation of activated rough glass carbon electrode (ARE) in KMnO4 solution and its electrocatalytic oxidation for Ascorbic acid (AA) were studied. The ARE showed higher electrochemical activity of ascorbic acid and its mechanism of catalysis was studied. In the buffer solution of pH 5.0, a sensitive oxidation peak of AA was observed at 0.17V at ARE, which is 500mV more negative than on flat glassy carbon electrode. The oxidation peak of AA is linear with its concentration from 4×10-6mol/L to 8×10-4mol/L in the pH 5.0 buffer solution (R=0.9993), Detectian limit of it reached 1×10-6mol/L. ARE had been successfully applied to the determination of AA in medicament sample.
