Adsorption of the Polyvinylidene Fluoride-Based Metal Affinity Membrane towards Bovine Serum Albumin

Abstract:

Three kinds of polyvinylidene fluoride (PVDF)-based immobilized metal affinity membranes (IMAM), namely, Cu (II)-IMAM, Co (II)-IMAM and Ni (II)-IMAM were prepared to recover bovine serum albumin (BSA) from the solutions. Adsorption of the aforementioned membranes towards BSA were studied with the presence of Ca (II) and PO₄^3–. The adsorption performance of the membranes followed the order of Co (II)-IMAM > Cu (II)-IMAM > Ni (II)-IMAM. The existent PO₄^3– exhibited a larger interference on BSA uptake than Ca (II).
