Description
A new inorganic cation-exchange membrane was successfully prepared on a microporous alumina substrate by dipcoating an antimonic acid sol solution obtained from a mixture of antimonic acid sol: Si(OC2H5)4: H2O: C2H5OH: HCl=O.06: 1: 11: 6.8: 0.068 in molar ratio.
The thickness, resistivity and ion-exchange capacity of the membrane increased with an increase in the number of dipcoated times, while the limiting currnet density showed a tendency to decrease.
The ion-exc hange capacity, area resistivity, limiting current density and transport number of Na+ for the 10 times coated membrane were O.0061 meq·cm-2, 186.2 Ω·cm2, 0.96 A·dm-2and O.70, respectively.
The mem branes could stand in 6 M hydrochloric acid or nitric acid aqueous solution at 80°C for 24 h without any change in ion-exchange capacity.
