The Green Preparation of Cellulose Fibrils from Oil Palm Leaf Stalk Fibers for Hydrogel Applications

摘要

In this study cellulose fibrils were successfully prepared from oil palm leaf stalk fibers by treated with water. The oil palm leaf stalk fibers were treated with water at 80 °C for 8 hours and bleached with 10% NaOCl at room temperature for 2 hours. The treated fibers showed a light-yellow color and had % yield around 76.50 wt.%. The fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA) indicated the removal of lignin and hemicellulose. The FT-IR peaked around 1725 cm-1, that indicated that the peak of lignin and hemicellulose disappeared when the oil palm fibers were treated with water. Moreover, the scanning electron microscope (SEM) micrograph showed a grooved surface due to the removal of lignin and hemicellulose from the outer surface of the oil palm fibers.
