摘　　要：运用高性能静态二次离子质谱从中国贵州 (六枝 )超高硫原煤有机相中观测到元素硫与铁的复合组成离子。由此 ,首次以确切的实验证据支持了过去关于煤中可能存在铁 硫复合结构的理论推测 ;同时本工作还表明 ,所采用的超高灵敏度和微区离子探针分析方法 ,适于今后进一步探索硫及其它有害元素在煤中的复杂化学赋存状态。The complex of elemental sulfur binding with iron in organic phase of coal is primarily observed by a high performance static secondary ion mass spectrometry(TOF SIMS)when a super-high sulfur coal, located at Guiding of southwestern China, is used as the test sample.This observation,as the first evidence,experimentally supports the theory of possible occurrence of iron-polysulfur complex in coal suggested recently. Meanwhile, the micro ion probe with high mass resolution and super-high sensitivity, the TOF SIMS used here, is demonstrated to be available for further approaching some complicatedly chemical states of sulfur or other harmful elements existing in coal.
