Zirconium was extracted as its anionic complex with various mineral acids by liquid anion exchanger. The chlorocomplex of zirconium was extracted from 6-10 M hydrochloric acid with trioctylamine, triisooctylamine or Aliquat 3365. The sulphotocomplex of zirconium was extracted with Aliquat 3365, Primine JMT, Alamine 336. The nitratocomplex was less extensively utilised for the extractive separation of zirconium. Zirconium was extracted quantitatively from oxalate and malonate media. These extractions were carried out at low pH and separated zirconium from large number of associated elements. The ion exchange chromatographic behaviour of zirconium on column with cation exchange or with anion exchange resin with citric acid as eluent were utilised but extraction studies from citrate solutions were never attempted. From the critical study of existing methods it was observed that zirconium was extracted at narrow pH range; with high concentration of complexing ligand for extraction with liquid anion exchangers and long period of equilibration for extraction as well as stripping. So also such extractions were possible mostly at milligram concentrations involving use of hazardous diluents like benzene. Therefore this paper presented systematic investigations on the solvent extraction separation of zirconium from citrate media with liquid anion exchangers.
