dc.descriptionExtraction behaviour of Ce(IV) from salicylate medium has been studied with the using N-n-octylaniline in xylene as an extractant. Cerium(IV) was completely recovered from the organic phase using 2.0 M hydrochloric acid and determined spectrophotometrically as complex with Arsenazo III. The influence of equilibrium pH, extractant concentration, stripping agents, equilibration time, nature of diluents, and diverse ions on the extraction of Ce(IV) was investigated. The stoichiometry of the extracted species was determined on the basis of slope analysis. The separation of Ce(IV) was carried out from some associated metals like U(VI), Th(IV), La(III), Y(III), Zr(IV), Nb(V), Gd(III) and Nd(III). The method presented is simple, reproducible, rapid and has been successfully applied for the determination of Ce(IV) in synthetic mixture, semiconductor films and monazite sand.
