Stability of membranes containing organophosphorus agents impregnated on a nucleoporous support in pertraction systems of REEs [Th. Ngo Manh, R. Kopunec] Stability of liquid membranes containing TBP, TOPO and HDEHP in n-dodecane, impregnated on a flat-sheet nucleoporous support, has been studied in pretraction systems of REEs. Under conditions of long-time uninterrupted pertraction, no signs of "failed” membrane behavior were observed in any system investigated. In regard to permeability coefficient of metal under the same conditions without regeneration of membrane, SLMs containing TOPO appeared the most stable, then SLMs containing HDEHP followed and the less stable were SLMs with TBP.
