Procédé pour le contrôle du pH lors de la séparation des terres rares par chromatographie sur échangeurs d’ions
(NH4)3H-EDTA-solutions of relatively high concentration can be used for the separation of the rare earths by complex-elution on ion-exchangers. The available acidity of the elutriant is determined acidimetrically in the présence of zinc sulfate; calculated amounts of HCOONH4 or CH3COONH4 are added...
