Abstract

The effect of sample preparation on the analysis of coal for metals is reported. Wet and dry ashing methods were investigated for the dissolution of coal samples. Nitric acid was the primary oxidizing acid. Sulfuric and perchloric acids were also used and their effect on the results is reported. Hydrofluoric acid was used to dissolve any siliceous material present in the coal. Different acid combinations were investigated for the dissolution of high temperature coal ash. The effect of particle size on oxidation was also investigated and the results are reported. A National Bureau of Standards’ coal sample was analyzed. The results were used to test the accuracy and precision of a method under investigation against an established method of analysis.
