A hydrochloric acid evolution method using stannous chloride as a promoting agent was developed and employed successfully for ferrous sulfides determination in 1400/degree/F coal char. This method not only provides an accurate analysis of ferrous sulfides, but also improves the accuracy of the organic sulfur analysis of coal char. We believe this method could be and should be employed in the sulfur-by-types analysis of all coal derivatives containing ferrous sulfides.
