【摘要】 在玻碳电极表面上成功地构筑了一种仿生膜———磷脂浇铸膜。将多巴胺固定在膜内 ,研究了其对 2 .0× 1 0 - 3mol L的抗坏血酸的催化氧化作用 ,抗坏血酸的氧化过电位被降低了大约 2 60mV。更多还原

【Abstract】 A kind of mimetic biomembrane--cast lipid film was made onto a glassy carbon electrode. Dopamine can be incorporated into the film. The oxidation of 2.0×10 -3 mol/L ascorbic acid with dopamine in the film was investigated. The oxidation overpotential of ascorbic acid was reduced by about 260 mV.更多还原
