Separation of Zirconium by Extraction Chromatography with Amberlite LA-1 from Malonic Acid

Zirconium was separated by extraction chromatography with Amberlite LA-l as an extractant from 1 × 10−3 M to 2.5 to 10−1 M of malonic acid at pH 2.0 to 6.0. It was stripped with various mineral acids and determined spectro-photometrically with arsenazo-III at 665 nm. Zirconium was separated from alkali, alkaline earths, yttrium, lanthanum, chromium(III), manganese, cobalt, nickel, copper, zinc, cadmium and aluminium by process of selective extraction. It was also separated from scandium, titanium, thorium, uranium and bismuth by process of selective stripping with various mineral acids. The method was extended for the analysis of zirconium in zircon.
