Abstract

Se describe un método para producir una solucion acuosa de un ácido aminocarboxílico de una solucion acuosa de una sal de metal alcalino del ácido aminocarboxílico. El primer paso del método es ajusta el pH de la solucion acuosa de la sal de metal alcalino del ácido aminocarboxílico a entre 1.0 y 3.0. Esto se hace añadiendo un ácido inorgánico monovalente a al solucion acuosa de la sal de metal alcalino del ácido aminocarboxílico para formar una solucion de alimentacion acuosa conteniendoácido aminocarboxílico protonado y una sal alcalina inorgánica teniendo un anion inorgánico y un cation de metal alcalino. El segundo paso del método es pasar la solucion de alimentacion acuosa a través de por lo menos una membrana usando un proceso de diafiltracion para separar la solucion de alimentacion acuosa en una solucion de permeato acuosa conteniendo el cation de metal alcalino y una solucion de retentato acuosa conteniendo el ácido aminocarboxílico.
