Title: SEPARATION OF MAGNESIUM FROM SODIUM AND POTASSIUM. A TRACER STUDY

Abstract

The production of magnesium-28 by pile-produced tritons simultaneously- results in considerable sodium-24 contamination. The degree of contamination was determined for magnesium precipitates by precipitating magnesium ammonium phosphate, magnesium oxalate from homogeneous solution, and magnesium-8- quinolinolate both by the conventional method and from homogeneous solution. The extent of sodium and potassium coprecipitated decreased in the order: phosphate method (single precipitation)> phosphate method (double precipitation)> oxalate method> quinolinolate method> quinolinolate method from homogeneous solution. In this last case the amount of sodium coprecipitated per 69 mg of magnesium ranged from 0.02 to about 1 gamma for 0.4 to 4000 mg of sodium added. Adsorption is believed to be responsible for the contamination in most cases. TMe results show the quantitative accuracy and reproducibility of the magnesium-8quinolinolate procedure for precipitation from homogeneous solution. (auth)
