采用NaOH/H2O2水溶液体系对蔗渣进行预处理,利用N-甲基吗啉-N-氧化物(NMMO)对预处理蔗渣进行分离提纯,得到纯度较高的再生纤维素。利用红外光谱、扫描电镜、X-射线衍射、热重分析等测试手段对制得样品结构进行了表征。
Bagasse was pretreated by NaOH/H2O2, aqueous solution. Regenerated cellulose with high purity was obtained through separation and purification by N-methylmorpholine-N-oxide (NMMO). The structures of the prepared samples were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA).
