materials which represent reaction intermediates. In the current study, Raman spectra in situ during the alkali treatment process were used to identify the presence of the intermediates of the reactions, and reveal the reaction pathway to the alkali treatment process. Furthermore, X-ray diffraction (XRD) and Fourier transform infrared spectrometry (FTIR) analyses were used to identify the changes......
