FORMATION CONSTANTS OF THE COMPLEX SPECIES FORMED BY INTERACTION OF RARE- EARTH NITRILOTRIACETATE COMPLEXES WITH AN EQUIVALENT AMOUNT OF BASE
The formation constants of the RChOH/sup -/ species, formed by interaction of individual rare-earth nitrilotriacetate species and KOH at 25 deg C and an ionic strength of 0.1 were determined by the potentiometric method, i.e., computed from the pH values of equilibrium mixtures containing varying proportions of rare-earth complex and base. The relations of these constants to the ion-exchange separation of rare earths at high pH were discussed. (auth)
