Membranes Separation - an overview | ScienceDirect Topics

Membrane separation is another potential method that may be applied to metal recovery from spent HPR catalysts. The separation of active metals could be enhanced by introducing an iminodiacetate group on the membrane [732]. The metal adsorbed from the solution by the agent could be eluted by permeation of an HCl solution.
