Title (EN) SOLVENT AND ACID STABLE MEMBRANES, METHODS OF MANUFACTURE THEREOF AND METHODS OF USE THEREOF INTER ALIA FOR SEPARATING METAL IONS FROM LIQUID PROCESS STREAMS
(FR) MEMBRANES STABLES AUX SOLVANTS ET AUX ACIDES, LEURS PROCÉDÉS DE FABRICATION ET LEURS PROCÉDÉS D'UTILISATION ENTRE AUTRES POUR SÉPARER DES IONS MÉTALLIQUES DE COURANTS DE TRAITEMENT LIQUIDES
Abstract:
(EN) Solvent and acid stable ultrafiltration and nanofiltration membranes including a non-cross-linked base polymer having reactive pendant moieties, the base polymer being modified by forming a cross-linked skin onto a surface thereof, the skin being formed by a cross-linking reaction of reactive pendant moieties on the surface with an oligomer or another polymer as well as methods of manufacture and use thereof, including, inter alia separating metal ions from liquid process streams.
(FR) La présente invention concerne des membranes d'ultrafiltration et de nanofiltration stables aux solvants et aux acides. Lesdites membranes comprennent un polymère de base non réticulé possédant des fragments latéraux réactifs, le polymère de base étant modifié par formation d'une peau réticulée sur une de ses surfaces, la peau étant formée par une réaction de réticulation des fragments latéraux réactifs sur la surface avec un oligomère ou avec un autre polymère. L'invention concerne également des procédés de fabrication desdites membranes et leurs procédés d'utilisation, notamment, en autres, la séparation d'ions métalliques de courants de traitement liquides.
