Abstract

MEMBRANAS SEMIPERMEABLES A UN GRAN FLUJO QUE COMPRENDEN UN PRODUCTO DE REACCION POLIMERIZADO DENTRO Y/O EN UN SOPORTE POROSO SE PUEDEN PREPARAR O PONER EN CONTACTO EL SOPORTE POROSO TAL COMO UNA LAMINA DE POLISUFONA CON UNA SOLUCION ACUOSA DE POLIAMINA, CONTENIENDO DICHA SOLUCION ACUOSA UN SOLVENTE APROTICO POLAR NO REACTIVO CON AMINAS Y OPCIONALMENTE UN RECEPTOR ACIDO. LA SUPERFICIE DE SOPORTE RECUBIERTO SE SECA AL TACTO Y DESPUES SE PONE EN CONTACTO CON UNA SOLUCION ORGANICA DE UN HALURO ACIDO POLICARBOXILICO DURANTE UN PERIODO DE TIEMPO SUFICIENTE PARA FORMAR UN PRODUCTO DE REACCION POLIMERIZADO DENTRO Y/O EN LA SUPERFICIE DEL MATERIAL DE SOPORTE. EL COMPUESTO RESULTANTE PUEDE SOMETERSE A UN TRATAMIENTO POSTERIOR LAVANDOLO CON UN COMPUESTO ALCALINO. EL COMPUESTO DE MEMBRANA RESULTANTE SE PUEDE UTILIZAR EN PROCESOS DE SEPARACION TALES COMO LA DESANILIZACION DE AGUA DE MAR O SALOBRES, O LA SUAVIZACION DE AGUAS DURAS DOMESTICAS.
