摘要
采用锡林浩特褐煤为原料,利用活化法提取腐植酸,运用傅立叶红外光谱(FTIR)和钡离子交换法测定原煤和腐植酸含氧官能团的含量,探讨了褐煤、腐植酸与提取腐植酸后褐煤(残余煤)的基本结构单元和含氧官能团含量的变化。
The humic acid was extracted through active acid from the lignite in Xilinhot, and then the contents of humic acid and oxygen-con- taining functional groups in the lignite were determined by Fourier transform infrared spectroscopy （FTIR） and barium ion exchange method. The basic structural unit and the oxygen functional group content of raw lignite, humic acid and lignite with humic acid extracted （ residue coal） changed.
