| 中文摘要 | a stable lipid cast film was made by casting a lipid in chloroform onto a glassy carbon electrode. we imbedded a new mediator norepinephrine into this lipid cast film, which was considered as a biological membrane model. through electro catalytic oxidation of ascorbic acid by this system, the anodic overpotential was reduced by about 250 mv compared with that obtained at a bare glassy carbon electrode. the electrochemical behavior of norepinephrine in the cast film was controlled by diffusion. the obtained diffusion coefficient of ascorbic acid was 1.87 x 10(-5) cm 2 s(-1). the catalytic current increased linearly with the concentration of ascorbic acid in the range from 0.5 to 10 mm. using cyclic voltammetry, we obtained two peaks for ascorbic acid and uric acid in the same solution. the separation between the two peaks is about 147 mv.
