| Abstract: | Electrocatalytic activity of the carbon nanotube modified electrode for ascorbic acid(AA) was studied by cyclic voltammetry.The experimental results show that the carbon nanotube modified electrode has excellent electrocatalytic ctivity for AA.In comparison with the bare glassy carbon electrode,the oxidation peak potential of AA on the carbon nanotube modified electrode is negatively shifted 0.502 V and the peak current of AA increases about 78%.The oxidation peak current is linearly dependent on concentrat... |
