Book Description
Excerpt from A Study of the Forms in Which Sulphur Occurs in Coal, Vol. 111 For some time sulphur in coal has been known to be combined with iron as iron pyrites and marcasite, both of which have the formula fesz. Very small quantities of sulphates also are found, but the amount is so small, especially in freshly mined coal, that it is almost negligible. Free sulphur has been suspected to be present in coal, but its presence is the exception rather than the rule. Iron pyrites is undoubtedly the chief inorganic sulphur compound found in any great quantity in coal. There are many indications that organic sulphur compounds form a large part of the sulphur in coal, but the nature of these compounds or the amount of sulphur so combined has never been determined prior to this investigation. Since the organic sulphur had its source in the protein sulphur of the plant and animal life from which the coal was formed, it is probable that these compounds in the coal are degradation 'products of the original material.

Book Description
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.
