Abstract

A precise Cottrell cell with glassy carbon electrode for chronoamperometric determination of diffusion coefficients is described. The validity of the measurement was demonstrated by comparing the observed diffusion coefficient of thallium(I) ions in 0.5 mol dm-3 KNO3 solution at 25°C with the standard value previously determined by the thin-walled hanging mercury drop electrode method. The essential points for successful measurement are a right choice of the material and a precise finish of that part of the cell where the diffusion is made to occur.
