| 摘 要： | 用傅立叶变换红外光谱（FTIR）方法对煤样进行了测试，研究了煤表面改性前后官能团含量的变化。结果表明，随着煤的变质程度增高，含氧官能团减少。当采用不同的电化学法还原处理后，不同变质程度煤的含氧官能团也都有不同程度的减少。含氧官能团的减少能使煤的疏水性增强，同时黄铁矿表面的亲水性增强，有利于浮选脱硫的进行。

| Abstract: | Coal samples were tested using the Fourie transform infrared spectroscopy (FTIR). Change of content of oxygenic groups on the surface of coal before and after surface modification was researched. The result shows that the oxygenic groups decrease with the increase of coal ranks. While after being treated with electronic method, the content of oxygenic groups of all ranks of coal decreases in a certain extent. The decrease of oxygenic groups can enhance the hydrophobicity of coal and decrease that of pyrite , making the separation of coal from pyrite be quite easy. So it is useful for the desulfurization of coal. |
