Solvent Extraction Separation of Zirconium (iv) With Anberlite LA - 1 From Citrate Solutions

Abstract

Abstract Zirconium was quantitatively extracted with 8 × 10−2 M of Amberlite LA-1 or LA-2 xylene from 0.001 M citric acid at pH 3.5 and it was stripped from the organic phase with 2 M hydrochloric acid and was determined spectrophotometrically at 665 nm as its complex with arsenazo III. Zirconium was separated from binary as well as tertiary mixtures by exploiting the difference in the distribution coefficient or by selective extraction or selective stripping. The method was applied for the analysis of zircon. 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 trioctylamine1–5, triisooctylamine6 or Aliquat 33657. The sulphotocomplex of zirconium was extracted with Aliquat 33658, Primine JMT9, Alamine 33610. The nitratocomplex was less extensively utilised for the extractive separation of zirconium11, 12. Zirconium was extracted quantitatively from oxalate13, 14 and malonate med...
