Abstract

EL CLORURO DE HIDROGENO SE SEPARA DE UNA RESINA DE INTERCAMBIO DE IONES BASICA AGOTADA MEDIANTE UN TRATAMIENTO CON UNA SOLUCION DE UNA AMINA TERCIARIA QUE SE ENCUENTRA EN UN SOLVENTE DE AMIDA. LA SOLUCION ELUENTE SE TRATA CON AMONIACO ANHIDRO PARA PRECIPITAR CLORURO AMONICO. LA SOLUCION DE AMINA TERCIARIA DEL SOLVENTE DE AMIDA SE SEPARA DEL PRECIPITADO Y SE PUEDE UTILIZAR PARA REGENERAR LA RESINA AGOTADA.
