Analysis of Steelmaking Slags by Atomic Absorption Spectrophotometry Using Pressure Dissolution.

摘要

A goal of the U.S. Department of the Interior,Bureau of Mines,is the advancement of minerals technology through the development of improved metals and minerals processing. In support of this goal,the Albany Metallurgy Research Center has developed atomic absorption spectrographic methods for the rapid analysis of Al2O3,CaO, Fe2O3,MgO,MnO,and SiO2in steelmaking slags. The application of these methods is discussed using an inexpensive pressure dissolution system. The overall coefficient of variation is 5pct. The accuracy is the same as the reproducibility.
