Abstract

The synergic extraction of Sm and Gd using a mixture of tributyl phosphate and Aliquat 336 is presented. The influence of diluents, salting-out agents and acidity on the synergic extractions have been investigated. The separation factor of Sm and Gd was found to be larger than 3. This is one of the best systems for the separation of Sm and Gd. NH/sub 4/NO/sub 3/ was found to be extracted by pure TBP or pure Aliquat 336, but cannot be extracted by a mixture of TBP and Aliquat 336.
