| Abstract: | Rare-earth salts of heteropoly modified glassy carbon electrode was prepared and the electrochemical characteristics of dopamine in the modified electrode were studied.The results showed that the modified electrode had promoting effects on the dopamine electrochemical oxidation compared with bare glassy carbon electrode,and electrocatalytic oxidation of dopamine was the surface-controlled process.The modified electrode had good stability and reproducibility. |
