摘要：

Experimental verification of the theory for the transient current response of a wall-jet electrode to a potential step is given. The systems studied are ferrocyanide and bromide oxidation in a specially designed large volume cell. Good and reproducible agreement between diffusion coefficients determined by this method and independent techniques is found. Optimized conditions, to avoid on the one hand the necessity of subtracting double-layer charging currents and on the other radial diffusion contributions, are defined.
