| Abstract: | The humic acid was extracted through active acid from the lignite in Xilinhot,and then the contents of humic acid and oxygen-containing 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. |
