应用X射线光电子能谱(XPS)研究了非挥发性和固体烃中有机结合态硫的形态和定量问题。模型化合物的XPS结果被用来解释煤和重质石油样品中的硫2P信号，即烷基硫化物和类硫杂菲的数量。伊利诺伊州6号煤中有机硫形态的测定是通过仔细监测铁硫化物和硫酸盐的贡献以及对重质石油样品的曲线分解方法的应用而完成的。XPS数据表明，在未氧化的伊利诺伊州6号煤和Raša煤中，硫以硫的形式存在。
X-ray photoelectron spectroscopy (XPS) was applied to the problem of speciating and quantifying organically bound forms of sulphur in non-volatile and solid hydrocarbons. XPS results from model compounds were used to interpret sulphur 2p signals from coals and heavy petroleum samples in terms of the amounts of alkyl sulphide and thiophen-like forms present. The determination of organic sulphur forms in Illinois No. 6 coal was accomplished by carefully monitoring the contributions due to iron sulphides and sulphates and application of the curve resolution method used with heavy petroleum samples. XPS data indicate that thiophenic sulphur forms the majority of the organic sulphur species in unoxidized Illinois No. 6 and Raša coals.
