Potassium copper hexacyanoferrate (KCuFC) had higher Rb sorption than other forms.
- class="label">•
KCuFC encapsulated with polymer (KCuFC-PAN) was well suited for dynamic column.
- class="label">•
KCuFC-PAN in fixed-bed column regenerated well in Rb sorption/desorption cycles.
- class="label">•
KCuFC-PAN showed Rb selectivity over a wide concentration of saline brine ions.

Rb was purified from K/Rb mixed solution using an ion exchange resin.
