中文摘要	this article describes a quantitative study of the diffusion rate of ferrocene(fc) dissolved in ploy(ethylene glycol)(peg) medium containing mclo(4)(m = li+, na+, bu(4)n(+), hx(4)n(+)). the apparent diffusion coefficient d-app and the active concentration c(a) of fc were simultaneously measured by using non-steady-state chronoamperometry. the d-app and c(a) of fc have been estimated in peg containing different concentrations and sizes of supporting electrolyte, and the dependence of d-app on ferrocene concentrations has been observed. the values of d-app decrease with increasing concentrations of fc, increasing concentrations of liclo4 or the ratio (o:li) and also with 4 decreasing cation radius of the electrolyte. the temperature dependencies conform to a simple free volume model. the concentration and size of the counterion dependencies of the diffusion rate are similar to the behavior of their dependencies of ionic conductivity in polyelectrolyte.
