摘要：
In this paper, the migration of Ca2+, Mg2+, Na+ and K+ in cation-bed electrodeionisation was studied. The results showed that it was longer for divalent cations to be balanced compared with monovalent cations. At relatively low current densities, the membrane fluxes of monovalent cations were higher than that of divalent cations, whereas the results were reversed at relatively high current densities. In the resin phase, it was observed that the ionic transport was in relation to various hydration ionic radii. The reaction orders for Ca2+, Mg2+, Na+ and K+ were 2, 2, 1 and 1.5, respectively.
