Web2 jan. 2013 · The correction factor of the highly hydrated ion Ca 2+ in PVA-based membranes is smaller than that of the Cl − (α Ca = 0.60, α Cl = 0.94) . The radius of the hydrated Na + is lower than that of the Cl −. Hence, α Na / α Cl is lower than 1.0. The result indicates that the transport number can be estimated from the value of the effective ...
