Abstract
MEMBRANAS SEMIPERMEABLES DE HIPERFLUJO SECO MEMBRANAS SEMIPERMEABLES DE HIPERFLUJO QUE COMPRENDEN UN PRODUCTO DE REACCION POLIMERIZADA DENTRO Y/O SOBRE UN MATERIAL REFLECTANTE DE SOPORTE POROSO PUEDEN PREPARARSE MEDIANTE EL CONTACTO DEL SOPORTE POROSO COMO UNA POLISULFONA CON UNA SOLUCION ACUOSA DE UNA POLIAMIDA QUE PUEDE, SI ASI SE DESEA, CONTENER UN DISOLVENTE APROTICO POLAR QUE NO REACCIONE CON LOS AMINOS, UN COMPUESTO POLIHIDRICO Y UN ACEPTOR DE ACIDO. LA SUPERFICIE DEL SOPORTE RECUBIERTO SE LIBERA DE EXCESO DE SOLUCION Y POSTERIORMENTE SE PONE EN CONTACTO CON UNA SOLUCION ORGANICA DE UN HALURO POLIACILO DURANTE UN PERIODO DE TIEMPO SUFICIENTE PARA FORMAR UN PRODUCTO DE REACCION POLIMERIZADO DENTRO Y/O SOBRE EL MATERIAL DE SOPORTE. EL COMPUESTO RESULTANTE SE TRATA A CONTINUACION CON UN ACIDO POLICARBOXILICO DE HIDROXIDO, UN ACIDO POLICARBOXILICO POLIAMINOALKILENO, ACIDO SULFONICO, SALES AMINAS DE ACIDOS, AMINOACIDOS, SALES AMINOACIDAS, ACIDO POLIMERICO Y ACIDO INORGANICO, ANTES DEL SECADO DE LA MEMBRANA. ESTO PERMITIRA QUE LA MEMBRANA SE ALMACENE DE FORMA SECA ANTES DE UTILIZAR LA MISMA EN UN PROCESO DE SEPARACION. EL COMPUESTO DE LA MEMBRANA RESULTANTE PUEDE UTILIZARSE EN PROCESOS DE SEPARACION COMO DESALINACION DE AGUAS SALOBRES O MARINAS O EL ABLANDAMIENTO DE AGUA DOMESTICA DURA.
