摘  要:
以富含纤维素的豆渣为原料,探究纳米豆渣纤维素的理化性质,并通过透射电镜、X射线衍射仪、综合热分析仪对所制备纳米豆渣纤维素进行表征,研究其结构与性质。所制备的纳米豆渣纤维素呈微球状,颗粒尺寸为15~50nm,仍属于纤维素Ⅰ型,结晶度为43.28%,晶粒平均尺寸为5.9nm,其膨胀力、重金属离子吸附能力较超微粉碎豆渣纤维素大,持水力、持油力较原料低。

摘  要:
In this study,nano-crystalline cellulose was prepared from soybean dregs(rich in cellulose) and used to investigate its physicochemical properties.Moreover,its structure was characterized using transmission electron microscope,X-ray diffractometer and comprehensive thermal analyzer.The prepared nano-crystalline cellulose was microspheres with particle size between 15 nm and 50 nm and still belonged to crystalline cellulose type Ⅰ.The crystallinity and average grain size were 43.28% and 5.9 nm,respectively.The nano-crystalline soybean dregs cellulose had higher expansive force and heavy metal ion-adsorbing capacity but lower oil-holding and water-holding capacities than the superfine soybean dregs cellulose.
