STUDIES OF QUANTITATIVE METHODS FOR THE SEPARATION AND DETERMINATION OF ZIRCONIUM AND THORIUM IN MAGNESIUM ALLOYS

摘要

This paper describes the results of a comparative study of analytical methods suitable for the determination of thorium end zirconium in magnesium base alloys.nIn addition, this paper describes en attempted amalgamation of selected analytical methods and ion exchange techniques into a scheme for the quantitative analysis of thorium and zirconium in these alloys. Manganese and zinc, common constituents of magnesium base alloys, were carried in the experiments, but only to study their interference in the proposed scheme.nThe sample is dissolved in 12N-HC1 end the resulting solution is percolated through a column containing Lowex 2-X3 enion exchange resin. Magnesium and thorium pass through the column while zirconium, zinc, and manganese are absorbed. The latter elements are removed by eluting the column with water.
