Notes:
The complexes of the lanthanons (Ln) with ethylenediamine-tetraacetic acid (H4Y) appear to be very valuable for the separation of the cerit earths. Three separation techniques have been investigated: (1) fractional precipitation of the free complex acids H[LnY], (2) fractional cristallization of their sodium salts in the presence of uncomplexed lanthanon ions and (3) fractional cristallization of their ammonium salts.
