Abstract
A new rotating diffusion cell is described in which a solute diffuses through a rotating filter. The transport of the solute to both sides of the filter is controlled by the rotation. The filter is filled with an organic phase. The rate of transfer of the solute through the filter is determined by the transport and by the kinetics of the interfacial transfer reactions. Since the transport is controlled the rate constant for the transfer reaction can be measured. Results for eleven different systems are reported and it is found that the rate constants are all smaller than 10−4 ms−1.This publication has 8 references indexed in Scilit:
