A method is described for the three commonly recognized forms of sulfur in coal, sulfate sulfur, pyrite sulfur, and organic sulfur. The sulfate sulfur is determined by extracting a weighed sample of coal with dilute HCl followed by gravimetric determination of the sulfate as BaSO/sub 4/. Extraction of a weighed sample of coal with dilute HNO/sub 3/ followed by titrimetric or atomic absorption determination of the iron in the extract yields a measure of the pyritic sulfur. Total sulfur in a weighed coal sample is determined according to ASTM Method 03177, and subtracting the sum of sulfate sulfur and pyritic sulfur from total sulfur yields a measure of the organic sulfur.
