| 中文摘要 | scanning electrochemical microscopy (secm) is employed to investigate the effect of solution viscosity on the rate constants of electron transfer (et) reaction between potassium ferricyanide in water and 7,7,8,8-tetracyanoquinodimethane (tcnq) in 1,2-dichloroethane. either tetrabutylammonium (tba(+)) or clo4- is chosen as the common ion in both phases to control the interfacial potential drop. the rate constant of heterogeneous et reaction between tcnq and ferrocyanide produced in-situ, k(12), is evaluated by secm and is inversely proportional to the viscosity of the aqueous solution and directly proportional to the diffusion coefficient of k4fe(cn)(6) in water when the concentration of tcnq in the dce phase is in excess. the k(12) dependence on viscosity is explained in terms of the longitudinal relaxation time of the solution. the rate constant of the heterogeneous et reaction between tcnq and ferricyanide, k(21), is also obtained by secm and these results cannot be explained by the same manner. |
