Study of XRD and FESEM Characterization of Cellulose from Hardwood Waste of Resak (<i>Vatica</i><i> spp</i>.)

Abstract

Cellulose is one of the most abundant biomass material in nature extracted from natural fibers. Its hierarchical structure allows different kinds of microfibril cellulosic fillers to be obtained known as cellulose microfibril or microfibrillated cellulose (MFC). MFC is generally prepared by either acid hydrolysis, or chemical treatments, or by a high pressure refiner. In this study, attempts have been made to extract MFC from Resak’s hardwood waste (Vatica spp.) at atmospheric pressure using single-stage peroxyacetic acid delignification and Totally Chlorine-Free bleaching methods. The morphology structure of samples were characterized using Field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD).

Preliminary Functional Group Study of Bacterial Cellulose Behaviour With and Without Acid Treatment

“…Other fingerprint regions for cellulose are peaks around 1300cm -1 indicating C-H bending and around 1400 cm -1 indicating CH2 bending [29]. The pure bacterial cellulose spectrum, distinguish peak of 3350 cm 1 O-H stretching, 2890 cm 1 indicates C-H stretching, 2360 cm 1 indicating Although fingerprint peaks can confirm the structure such as that of cellulose, the curve of peaks may vary, depending on the origin of cellulose. In addition, the spectra of bacterial cellulose from Acetobacter xylinum showed its own signature curve and this shape of curve was consistent and reproducible.…”

“…There are various types of tropical plants that can be extracted into cellulose, such as from Resak's hardwood waste (Vatica spp.) [1] and cellulosic material derived from merbau (Intsia bijuga) [2]. Either than tropical plants, cellulose can also be extracted by using pineapple leaves fibers (PALF) which are being wasted after fruit harvested [3].…”
