摘要：

The behaviour of citric acid during electrodialysis using model solutions was investigated. The limiting current densities were determined at various pH-values, concentrations and temperatures. Difficulties, which were encountered in establishing the limiting current densities using the Cowan and Brown method, are outlined. Furthermore, the mass transfers and water transports, corresponding to the limiting currents, were measured and illustrated.
