| Abstract: | In this paper,the second order rate coefficient for homogeneous catalytic re action of ferrocene and its derivative have been detendned by open circult relaxation diator in redox enzyme catalysis for the anaerobic oxidation of glucose catalyzed by glucose oxidase. Moreover, the feasibility and conditions for the application of the open circuit relaxation method is discussed. |
