Ion-Exchange Removal of Fe(III) and Mg(II) in the Analysis of Rare Earth Elements in Rocks by Inductively Coupled Plasma Mass Spectrometry

Abstract:

Tiron has been proposed for the removal of Fe (III) and Mg (II) ions from the test solution by ion exchange in the REE trace analysis in rocks by ICP-MS. The conditions for Fe (III) isolation on a column with anion-exchange resin АВ-17-8,Cl^– and for Mg (II) on a column with cation-exchange resin Purolite С100 have been found. The concentration of Fe (III) is reduced up to 10 times, and Mg (II) – more than 100 times. Correction factors have been used in order to eliminate the systematic error in the determination of REE due to their partial sorption on the anion-exchange resin in the form of complexes with Tiron. The correctness and accuracy of the developed sample preparation method and of the correction factors have been confirmed in the analysis of standard samples base on natural geochemical objects.
