| 中文摘要 | a ferrocene-dimyristoyl phosphatidylcholine (dmpc) film electrode was prepared by casting the solution of ferrocene and dmpc in chloroform onto a glassy carbon electrode surface. ferrocene retained in the biological membrane gave a couple of irreversible peaks of cyclic voltammogram. the electrode exhibited good electrocatalytic activity for the oxidation of ascorbic acid (h(2)a) in phosphate buffer (ph 6.64) with an anodic peak potential of +340 mv (vs. ag/agcl). the anodic current was directly proportional to the square root of the scan rate below 150 mv s(-1). the influence of the ph value was investigated and it was observed that ph 6.64 was the suitable value to the anodic peak potential and current. the thickness of the film and the interference of uric acid were also studied. the electrode can be used to determine h(2)a in the presence of equimolar uric acid. the catalytic peak current increased linearly with the concentration of h(2)a in the range of 1 x 10(-4)-5 x 10(-3) mol l-1. |
