摘要：
A flow-injection amperometric method for the determination of diffusion coefficients is described, involving the use of a platinum wire and a carbon tube flow-through detector on the basis that the limiting current response for flow-through electrodes is directly proportional to the two-thirds power of the diffusion coefficient of an analyte. The method is simple and rapid and has good accuracy. It is suitable for measuring the diffusion coefficients of electroactive substances in a variety of aqueous media.
