Abstract
Selon l'invention, on ajoute des ions phosphates à la solution contenant des cations polyvalents, y compris des ions calcium, la quantité d'ions phosphates étant supérieure à la quantité consommée dans la réaction des ions phosphates et des ions calcium, on ajuste le pH de la solution dans la région alcaline pour précipiter au moins les ions calcium dans la solution et on élimine le précipité. Ce procédé s'applique en particulier à la purification des solutions aqueuses d'halogénure de métal alcalin pour l'électrolyse selon un procédé à membrane échangeuse d'ions.
