NANOPOROUS, ALUMINIUM-SUPPORTED ALUMINA MEMBRANE, METHOD FOR PRODUCING SAME AND USE THEREOF

摘要

The present invention describes a membrane for removing anions from liquid media, preferably phosphorus, comprising an aluminium metal structure containing: . an inner layer with two faces, made of non-anodized and non-porous aluminium; . an outer layer that coats the inner layer and contains anodized aluminium oxide with nanoporosities, the pores in the nanoporosities having an essentially rectilinear structure. Also described in this patent application are the method for producing said membrane and the use of the membrane.
