“…Sulphuric acid and hydrofluoric acid media have greater affinities towards niobium and tantalum using TOA as reported by Das et al [18]. Yamani et alinvestigated that extraction of zirconium depends on acidity, metal and solvent concentration, diluent type and temperature by using tri-caprylmethylammoniumchloride from sulphate media [19]. Cerrai and Testa studied the extraction and separation of Zr and Hf with TOA and Aliquat-336 from hydrochloric acid media [20].…”

The extraction behavior of Zr(IV) with tri-n-octyl amine (TOA) in kerosene was studied through a new method of solvent extraction. The mechanism of extraction and the species extracted were identified. Quantitative extraction of Zr(IV) with TOA in kerosene was studied by changing different parameters such as acid variation, diluent effect, metal concentration variation, extractant variation, effect of salting out reagent concentration and effect of temperature. It was observed that the percentage of extraction of Zr(IV) increased when the concentration of TOA and the percentage of extraction also increased when the metal ion concentration increased. The percentage of Zr(IV) became 97.4% with 0.1 M TOA from 3.0 M sulphuric acid. Kerosene was found to be effective diluent for the extraction of Zr(IV) with TOA.
