Abstract

Una membrana de pelicula delgada compuesta y semipermeable emplea en el producto de la reacción de N-alquilfenilendiamina o N,N'-dialquuilfenilendiamina y un poliacilhálido como cloruro de trimesoílo. De preferencias la membrana esta tratada posteriormente con una solución acídica seguido por una solución acuosa de acohol polivinílico y un amortiguador y/o una base para mejorar sus características físicas.
