Abstract
The effective distribution coefficients of the cerium earth nitrates were determined with input of 100 g oxide, while those of the yttrium earths were estimated from former work. The values rise to a maximum at Dy, then decrease from Ho to Yb. The separation of cerium earths from each other was distinctly better with 11M HNO3 than with 4M HNO3.
