Molecular structure characterization of lignite treated with ionic liquid via FTIR and XRD spectroscopy

In order to characterize the effect of ionic liquid concentration on the molecular structure of lignite, the X-ray diffraction (XRD) and Fourier transform infrared (FTIR) experiments were performed on lignite coal samples treated with different concentrations of ionic liquids. The results show that...
