| Abstract: | The preparation of electrode modified by polyalizarin membrance was described in this paper. The electrode has strong electro-catalytic effect on the oxidation of catechol.The anodic peak potential of catechol shifted negatively by 70?mV,the peak currents add notably,and it's magnitude along with the inreasement of the catechol content,.The oxidation peak current of catethol is linear with its contentration from 2.0×10~(-6)mol/L to 1.0×10~(-4)mol/L.The modified electrode showed good stability and reproducibility. |
