ABSTRACT:
A process for preparing an ion-exchangeable media within a moving-bed or simulated moving-bed device, which can create a true or simulated media flow, comprising the steps of packing the bed with ion-exchangeable media and passing a solution, containing a mixture of ionic species, through the media, wherein the solution is passed partly or completely counter-current to the media flow direction such that the ionic species are loaded to a desired level upon equilibration.
