煤有机硫分析中xps分峰拟合方法及参数设置
, PP. 277-283
Keywords: 煤,有机硫,xps,劈裂峰,分峰拟合方法,参数设置
Abstract:
？通过对含硫模型化合物和新峪焦精煤中的有机硫含量的分析，对xps谱图的分峰拟合方法和参数设置进行了探讨。结果表明，用xps解析煤中不同形态硫含量时，应按2p3/2和2p1/2劈裂峰分峰方法进行，并设置劈裂峰的面积比约为2：1，裂距为1.18ev，l-g%相同，fwhm值也相同；限定各有机硫2p3/2峰峰位分别为：硫醇硫醚类硫162.1~163.6ev；噻吩类硫164.0~164.4ev；亚砜类硫165.0~166.0ev，同时对分峰拟合参数在一定范围内进行动态微调，可实现良好的数据重现性和较佳的拟合度。
