    • Abstract


      The behaviour of rare earth hydroxides towards variously concentrated solutions of sodium potassium tartrates is studied. Their solubility varies in the order Ceiii>La; that of erbium, yttrium and ceric is, however, found to be almost negligible. This suggests a fairly rapid method of separation of rare earths (a) yttrium and erbium from (b) lanthanum and cerous salts; and the fractionation of (b).
