ABSTRACT:
Pressure-driven affinity sorption membranes are prepared from a membrane filter composed of an insoluble matrix polymer or an interpolymer composite and used for separation and purification by passing therethrough solutions containing mixtures, one or more of which forms a specific complex with the ligand on the pore surface of the membrane, washing out the uncoupled solutes, then employing an appropriate displacing or eluting agent to recover the desired component in a pure and concentrated state, all under pressure-driven conditions.
