Abstract
Abstract Methods were developed for determining lime in magnesite by atomic absorption (AAS) and x-ray fluorescence (XRF) spectroscopy. The procedures were evaluated by using reference materials and commercial samples that had been analyzed gravimetrically. For AAS, samples are dissolved in HCl and the absorption is measured at 422.7 nm in a nitrous oxideacetylene flame. XRF determinations are made by using fused disks and a standard addition method. The intensity of the CaKα line corrected for background is measured. Regression analysis of the data shows that both instrumental methods are acceptable substitutes for the gravimetric procedure. Analysis of reference materials indicates that the methods are accurate. The AAS procedure is the simplest and fastest of the 3 methods.
