Supported liquid membranes: stabilization by gelation


Neplenbroek, A.M. and Bargeman, D. and Smolders, C.A. (1992) Supported liquid membranes: stabilization by gelation. Journal of Membrane Science, 67 (2-3). pp. 149-165. ISSN 0376-7388

Abstract:A new method has been developed to increase the stability of supported liquid membranes. By applying a homogeneous gel network in the pores of the support both the mechanical stability (against liquid displacement) and the long term permeability increase substantially. The flux decreases only slightly because of the open structure of the gel network. A second technique, by which a thin dense gel layer is applied to the feed side of the membrane, results in a specific suppression of the formation of emulsion droplets. The stability of the membrane increases by this treatment to values which are very promising.
