Abstract

Un proceso para purificar una solución acuosa de un haluro de metal alcalino para electrólisis que comprender añadir ión fosfato a dicha solución que contiene cationes polivalente que incluyen iones calcio siendo la cantidad de ión fosfato superior a la que se consume en la reacción del ión fosfato con los iones calcio, ajusta el pH de dicha solución a la región alcalina para precipitar al menos los iones calcio en dicha solución y eliminar el precipitado.
