STUDY OF THE ESTIMATION OF CERTAIN TRACE IMPURITIES BY FLUORIMETRIC METHODS. PART I.
Abstract
A comprehensive literature survey of the known fluorimetric reagents for aluminum, magnesium and silicon was carried out. Another extensive survey of separation methods was also made, to determine the best techniques for segregating microgram quantities of Al, Mg or Si from gram quantities of Ni, Ti, Mo, Ta, W, Re and the compound semiconductors. Microgram quantities of aluminum were isolated from gram quantities of molybdenum in HF/HC1 solution, using Amberlite IRA-400 resin columns. While some difficulties still remain to be solved, the ion-exchange technique appears to be applicable for the isolation of Al and Mg from Mo, W, Ta or Re. Mercury pool electrolysis has shown promising results for the elimination of nickel. (Author)
