摘要：
Surface characteristics of untreated and microwave-assisted dilute lye (MAL) treated rice straw have been investigated using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Rice straw composition was investigated by lignocelluloses determination. FTIR showed MAL treatment could effectively remove lipophilic extractives from the rice straw surface and break hydrogen bonds in the rice straw, and it was proven that more cellulose was exposed by MAL-treated with SEM. The composition analysis result indicated that the content of cellulose is 46.8% and content of lignin is 8.3% in rice straw with high-fire-power microwave-assisted 1% dilute lye for 1 h, and saccharification rate is 86% with high-fire-power microwave-assisted 1% dilute lye for 2 h.
