A procedure was developed for the direct determination ofeach of the sulphur forms in coai by using various strengths of perchloric acid as the selective oxidizing agent. Sulphate, sulphide, pyritic and organic sulphur were each determined sequentially on a single sample of coal. The oxidizing abili
