X-ray photoelectron spectroscopy (XPS) has been used to study the nature and content of sulphur contained in coal samples from Assam. In each case two sulphur 2p (S 2p) peaks were observed. The 169-I 71 eV 2p peak corresponds to sulphate, whilst the 164-I 65 eV peak is assigned to S in iron sulphide
