Excerpt from The Analysis of Sulphur Forms in Coal

Iron pyrites has been known as one of the constituents of coal for a great many years and investigators have had fairly good evidence that sulphur in organic combination also existed in coal. The first method proposed for the analysis Of these two forms utilized sodium hypobromite.2 The supposition was that the hypobromite dissolved the pyrites and sulphates without affecting the organic sulphur, but no proof was advanced to Show that this was correct.

Excerpt from The Analysis of Sulphur Forms in Coal

For certain purposes, however, it is desirable to know not only the total sulphur content, but also how the sulphur is combined in the coal and the exact amount of each form present. Data of this kind would be useful in indicating how much of the sulphur-containing material can be removed from the coal by washing processes, what effect the sulphur has on the heating value of the coal, how the various sulphur forms behave during the coking and gas-making processes, and other facts of interest to coal technologists.

The main purpose of this investigation, undertaken by the Bureau of Mines, however, was to try out further the method of Powell and Parr for the analysis of sulphur forms in coal (described on p. To determine its applicability to a variety of coals, and to introduce, if necessary, certain refinements of analysis. Preceding experiments had been chiefly with Illinois coals, so it was important. To ascertain just how the method would apply to coals from other districts.
