Liquid-liquid extraction of Zr(IV) from sulphuric acid medium using tri-n-octyl amine in kerosene

J. Swain, A. Sahoo and B. C. Bhatta

The extraction behaviour of Zr(IV) with tri-n-octyl amine (TOA) in kerosene has been studied through a novel method solvent extraction. The mechanism of extraction and the species extracted have been identified. Quantitative extraction of Zr(IV) with TOA was achieved in kerosene by changing different parameters such as acid variation, diluent effect, metal concentration variation, extractant variation, effect of chloride ion concentration and effect of temperature on extraction of Zr(IV) were studied. The percentage of Zr(IV) became 97.4% with 0.1 M TOA from 3 M sulphuric acid. Xylene was found to be effective diluent for the extraction of Zr(IV) with TOA.

Keywords: Zirconium, solvent extraction, sulphuric acid, tri-n-octyl amine (TOA), kerosene.
