Sulfur in coal and its environmental impact from

Sulfur is one of the hazardous elements in coal. The concentrations of sulfur are relatively high in coal. The major forms of sulfur in coal are pyritic, organic and sulfate. Pyritic and organic sulfur generally account for the bulk of sulfur in coal. Elemental sulfur also occurs in coal, but only in trace to minor amounts. When coals are burned, leached and washed, sulfur will be released in

Measuring Sulfur Content of Coal Using EDXRF

When coal is burnt, the metal equipment can get corroded rapidly due to the presence of higher sulfur content. Moreover, sulfur itself is an environmental pollutant when it burns. Hence, there is a requirement for a simple, yet rapid and robust tool to measure the sulfur content of coal for the characterization and value of the coal, from
