Ethanol/water organosolv pulping was used to obtain sugarcane bagasse pulp that was bleached with sodium chlorite. This bleached pulp was used to obtain cellulosic films that were further evaluated by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). A good film formation was observed when temperature of 74 degrees C and baths of distilled water were used, which after FTIR, TGA, and SEM analysis indicated no significant difference between the reaction times. The results showed this to be an interesting and promising process, combining the prerequisites for a more efficient utilization of agro-industrial residues.
采用乙醇/水有机溶剂法制浆来制备甘蔗渣浆,并用亚氯酸钠对其进行漂白。将这种漂白后的纸浆用于制备纤维素膜,然后通过傅里叶变换红外光谱(FTIR)、热重分析(TGA)和扫描电子显微镜(SEM)对其进行进一步评估。当使用74摄氏度的温度和蒸馏水浴时,观察到形成了良好的薄膜,经过FTIR、TGA和SEM分析表明反应时间之间没有显著差异。结果表明,这是一个有趣且有前景的工艺,满足了更高效利用农业工业残渣的前提条件。
