STUDY OF THE ESTIMATION OF CERTAIN TRACE IMPURITIES BY FLUORIMETRIC METHODS

Abstract

The preparation and development of a new fluorimetric reagent for magnesium is described. This is N,N'-bis salicylidene-2,3-diaminobenzofuran. The spectral characteristics of the magnesium complex are given together with evidence to show that this is the most sensitive magnesium reagent so far tested in this program. Details are given of work on the development of separation techniques for the removal of microgram quantities of magnesium from gram quantities of molybdenum and nickel. Full experimental data is presented concerning a new method for the determination of up to 2 p.p.m. magnesium in nickel.
