Liquid ion exchangers such as tri-n-octyl amine (TOA), tri-iso-octylamine (TIOA) and Aliquat 336 have been used in this laboratory for analytical separation of vanadium(V) and niobium(V), indium(III), thalium(III), thorium(IV), cerium(IV) from succinate solutions. Extension of this study has revealed that benzene solutions of TOA, TIOA and Aliquat 336 could be used for anion exchange extraction of quadrivalent titanium and zirconium from succinate solution. The metal ions from the organic phase are stripped and determined spectrophotometrically. Solvent extraction methods for titanium(IV) and zirconium(IV) have been reviewed by De et al. and Korkisch in their monographs. Diethylamine, tri-ethylamine and tributylamine have been used for extraction of titanium from thiocyanate and citrate solution. Similarly high molecular weight amines such as TOA and TIOA have been used for the extraction of zirconium from mineral acids, but systematic solvent extraction separation of titanium(IV) and zirconium(IV) is lacking. In this communication we propose a new method for selective extraction and separation of titaium(IV) and zirconium(IV) from metal ions such as Mn, Cr, Mo, V, U, La, Ta, Th and Hf. The proposed method is comparatively free from drawbacks such as pre-equilibration of phases, multiple scrubbing, multiple extraction and coextraction of a large number of cations and anions.
