SEPARATION OF YTTRIUM AND FISSION-PRODUCT RARE EARTHS BY ION EXCHANGE AT ROOM TEMPERATURE

Technical Report ·
OSTI ID:4298623
Determination of a large number of cross sections for the formation of yttrium and light rare earths in deuteron fission of uranium required a reliable chemical-separation method. In the method that has been used successfully, the separation is made using 8 to 15 mg of carriers on colloidal Dowex-50, eluting with 0.70M ammonium lactate, pH 3.30, at room temperature. Over-all chemical yields were regularly in the range of 80 to 85%, and adequate separation of adjacent rare earths was achieved. A disadvantage of the method is the relatively long time, about 35 hours, required for the elution through the neodymium band. (auth)
