Table 28. Monosulfide sulfur in coal
|Monosulfide Sulfur Concentrationa (percent)|
monosulfide sulfur concentrations not given by Alpha
Resources, Inc. (1985).
bMonosulfide sulfur concentrations measured in U.S. Geological Survey laboratories. Values shown for each coal standard are the arithmetic mean and standard deviation for n measurements, where n is the number in parentheses. For standard 771, three of the eight measurements indicated monosulfide sulfur concentrations of <0.01. The mean concentration shown is the average of the other five values.
