Various 3-phenyl-4-aroyl-5-isoxazolones, namely, 3-phenyl-4-benzoyl-5-isoxazolone (HPBI), 3-phenyl-4-(4-fluorobenzoyl)-5-isoxazolone (HFBPI) and 3-phenyl-4-(4-toluoyl)-5-isoxazolone (HTPI) were synthesized and examined with regard to the solvent extraction behavior of Zr(IV) and Hf(IV) from hydrochloric acid solutions. The results demonstrated that Zr(IV) and Hf(IV) extracted into chloroform with 3-phenyl-4-aroyl-5-isoxazolones (HA), as ZrOA

Ph Range

The extraction behavior of zirconium(IV) from succinate (0.01 - 0.03 M) medium (25 mL) with 10 mL 3 % N-n-octylaniline in xylene was investigated. The pH range 3.7 - 5.0 was effective for the quantitative extraction of zirconium(IV). Zirconium(IV) was back extracted with 0.5 M HNO3 (3 x 5 mL). The method was free from interferences of a large number of cations and anions. Zirconium(IV) was separated from associated elements in its binary mixture with Mo(VI), Nb(V), Re(VII), La(III), Ti(IV), Th(IV) and Al(III). The proposed method was applied to synthetic mixtures. The results of analysis indicate that trace amounts of zirconium( IV) could be separated effectively from higher amounts of other elements. The method is simple, selective, rapid and eco-friendly.
