摘要: In the case of an electrodialysis operation, it is possible to obtain limiting current by measuring conductivity solution undergoing dilution. Starting from equation constant flux matter, when concentration at membrane falls zero, (i/σd)crit = δ relates density i and diluate σd. The critical value (i/σd) easily obtained drawing σ dvs potential applied apparatus. Experiments carried on aqueous solutions KHC4H4O6 8 g/l show that (i/σd)crit) well related Reynold's number relation αReβ. It then calculate thickness diffusion layer as a function number.
