Method for separating sodium and potassium by ion exchange |
| 摘要 |
A method for separating sodium and potassium from an aqueous solution containing such metals, which comprises selectively ion-exchanging sodium and potassium with titania hydrate (TiO2xnH2O where n=1 to 2) obtained by treating potassium titanate to remove potassium therefrom, followed by a reaction at a temperature of from 25 DEG to 80 DEG C. to desorb and purify sodium and potassium.
