摘要：
X-ray absorption near edge structure (XANES) spectroscopy and X-ray photoelectron spectroscopy (XPS) were used to study the chemistry of organically bound sulphur species in coal during mild coal oxidation. Spectra of preserved and oxidized samples were obtained and compared. Both techniques indicate that sulphide sulphur forms are converted to oxidized forms while the thiophenic forms remain largely untouched under these experimental conditions. © 1990.
