Abstract

CE PROCEDE CONSISTE A SULFONER DES MEMBRANES POREUSES DE POLYMERES D'ACRYLONITRILE CONTENANT 40 A 100MOLES D'ACRYLONITRILE. LA MEMBRANE POREUSE A PAR EXEMPLE UN POINT DE BULLE SUPERIEUR A 1KGCM ET UNE PERMEABILITE A L'EAU DE 0,01 A 1000LMH SOUS UNE PRESSION DE 10KGCM. LA MEMBRANE SEMI-PERMEABLE RESULTANTE EST UTILISABLE TRES AVANTAGEUSEMENT POUR LA SEPARATION DE SUBSTANCES PAR OSMOSE INVERSEE OU ULTRA-FILTRATION.THIS PROCESS CONSISTS OF SULFONING POROUS MEMBRANES OF ACRYLONITRILE POLYMERS CONTAINING 40 TO 100 MOLES OF ACRYLONITRILE. THE POROUS MEMBRANE HAS FOR EXAMPLE A BUBBLE POINT GREATER THAN 1KGCM AND A WATER PERMEABILITY OF 0.01 TO 1000LMH UNDER A PRESSURE OF 10KGCM. THE RESULTING SEMI-PERMEABLE MEMBRANE CAN BE USED VERY ADVANTAGEOUSLY FOR THE SEPARATION OF SUBSTANCES BY REVERSE OSMOSIS OR ULTRA-FILTRATION.
