Self adduct formation in the extraction of uranium [VI] chelate of 8-quinolinol

ABSTRACT

Tremendous amount of work has been done on the metal chelate system in which any one kind of ligand is involved in chelation. The effect of such factors as ligand basicities, sizes of chelate rings, steric factors and metal ion acidity have been evaluated in the formation of a chelate from the aquated metal ion and the chelating agent. The extraction of coordination - unsaturated chelates can, in some cases, be favoured by the use of an excess of chelating agent. Despite the contributions from several authors to the formation of uranium oxinate complexes, it is interesting that the composition and other characteristics of the extracting uranium-oxine system are not established with certainty. The present study attempts to throw more light on these aspects
