摘要: Rice husk powder was oxidized in aqueous sodium hypochlorite solution under mild conditions with different reaction times. Fourier transform infrared spectroscopy, gas chromatography-mass spectrometry (GC-MS), and direct analysis real time-mass (DART-MS) were used to analyze the oxidation products. Results showed that a feasible way depolymerize macromolecules biomass convert hydroxyl groups carboxyl groups. In total, 113 organic compounds products molecular mass less than 500 Da identified using GC-MS. As an ambient ionization technique, DART-MS applied determination of derivatives revealed distribution structure information for rice
