研究了在pH 7.0的磷酸盐水溶液中，用非离子去污剂增溶二茂铁的电化学行为。二茂铁分子作为胶束被引入，其容易与铂电极转移电子。循环伏安和电位数据表明，电子转移反应是可逆的。从电化学扩散和光散射数据计算的胶束尺寸给出了40- 45 A之间的半径和约40 - 45 A的分子量。130,000.二茂铁胶束是一种优良的介体滴定剂，能偶联电极与细胞色素c、细胞色素c氧化酶及其混合物的海涅蛋白质之间的电子传递，近年来，在pH 7.0的水溶液中，用非离子去污剂增溶二茂铁，电生成的铁离子可用于细胞色素c、细胞色素c氧化酶及其混合物的氧化还原滴定（I）。洗涤剂显然形成胶束与二茂铁的掺入。然后，将铁/二茂铁对
The electrochemistry of ferrocene solubilized by the use of nonionic detergent in aqueous phosphate solutions pH 7.0 was studied. The ferrocene molecules were incorporated as micelles which readily transferred electrons with a platinum electrode. Cyclic voltammetric and potentiometric data indicated that the electron transfer reaction was reversible. Micelle size calculated from electrochemical diffusion and light scattering data gave radii between 40-45A and molecular weights of ca. 130,000. The ferrocene-micelle served as an excellent mediator-titrant to couple electron transfer between an electrode and the heine proteins of cytochrome c, eytochrome e oxidase, and mixtures thereof.Recently, ferricinium ion electrogenerated from ferrocene solubilized by the use of nonionic detergent has been employed Zor the redox titration of cytochrome c, cytochrome c oxidase, and mixtures thereof in aqueous pH 7.0 solutions (I). The detergent apparently formed micelles with the incorporation of ferrocene. The ferricinium/ferrocene couple is then
