Complexation and extraction of series 4f, 5f and 4d ions by dialkyldithiophosphoric acids
Description
A study was carried out on the complexing and extracting properties of various dialkyldithiophosphoric acids towards ions of the 4f, 5f and 4d series. Sulphurated donors complex and extract ions of the 4f and 5f series less strongly than their oxygenated homologues. However the affinity of trivalent actinide ions for dialkythiophosphate ions is shown to be greater than that of lanthanides. The conditions of ruthenium extraction from nitric acid are defined.

Abstract (French)
Une etude des proprietes complexantes et extractantes de divers acides dialkyldithiophosphoriques, vis-a-vis d'ions des series 4f, 5f et 4d, est realisee. Les donneurs soufres sont des complexants et des extractants des ions des series 4f et 5f, moins forts que leurs homologues oxygenes. Neanmoins, on a montre que l'affinite des ions actinides trivalents pour les ions dialkyldithiophosphoriques etait superieure a celle des lanthanides. Les conditions d'extraction du ruthenium de solution nitrique ont ete definies. (auteur)Files
