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

In this study, the solvent extraction of Pd(II) from hydrochloric acid solutions was investigated using the new synthesized material, 2-ethylhexyl benzothiazolyl sulfide (EHBTS) which was dissolved in xylene. Pd(II) was strongly extracted by 7% EHBTS in a lower concentration hydrochloric acid solution. Extraction parameters of Pd(II), including EHBTS concentration in different diluents, contact time of aqueous and organic phases, organic/aqueous (O/A) phase ratio and HCl concentration of aqueous phase, were studied. Quantitative extraction of Pd(II) occurred at 0.1 mol.L-1 of HCl concentration, 7% of EHBTS concentration, 1.0 of O/A, 40 min of contact time. In addition，the percentage stripping of Pd(II) could be more than 98% when thiourea concentration was 0.8 mol.L-1. EHBTS can be used more than 8 as extractant to extract of Pd(II) from hydrochloric acid solutions.
