Abstract: front page image
(EN)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.
(FR)La présente invention concerne une membrane pour l'enlèvement d'anions dans des milieux liquides, de préférence du phosphore, comprenant une structure métallique en aluminium, laquelle comporte: - une couche intérieure à deux faces, constituée d'aluminium non anodisé et non poreux; - une couche extérieure qui recouvre ladite couche intérieure et qui contient de l'oxyde d'aluminium anodisé avec nanoporosités, les pores dans lesdites nanoporosités possédant une structure essentiellement rectiligne. La présente demande de brevet concerne en outre un procédé d'obtention de ladite membrane ainsi que son utilisation.
(PT)A presente invenção descreve uma membrana para remoção de aniões em meio líquidos, preferencialmente fósforo compreendendo uma estrutura metálica em alumínio a qual contém: • uma camada interna com duas faces, de alumínio não anodizado e não poroso; • uma camada externa que reveste a referida camada interna, a qual contém óxido de alumínio anodizado com nanoporosidades, em que os poros das referidas nanoporosidades possuem uma estrutura essencialmente rectilínea. São ainda apresentados neste pedido de patente, o método de obtenção da referida membrana e a sua utilização.
