Abstract

The Teflon bomb and the flameless atomic absorption spectrophotometer (AAS) were used to analyze trace metals in Wyoming coal The results were compared to a National Bureau of Standard (NBS) reference coal sample. The combined use of the Teflon bomb and flameless AAS appears to be a sensitive, accurate, and practical method for analyzing trace metals in coal. Most metallic concentrations in Wyoming coal samples do not appear to exceed the collected U.S. coal samples.
