Abstract

Se revela un método para preparar sistemas camas mezcladas de resinas no aglomeradas, para intercambio de iones, sin afectar la cinética de intercambio de ion del componente de la resina de intercambio de anion del sistema de cama mezclada. El tratamiento previo del componente de la resina de intercambio e anion con un polielectrolito poli(vinilaromático) sulfonizado es particularmente efectivo para proporcionar sistemas de cama mezclada no aglomerada sin afectar la cinética de intercambio de ion. Se prefieren de forma particular los niveles de intercambio de anion con un polielectrolito poli(vinilaromático) sulfonizado que tiene un peso molecular promedio en numero de 5,000 a 1,000,000.
