FTIR, XRD and SEM Analysis of Microcrystalline Cellulose (MCC) Fibers from Corncorbs in Alkaline Treatment

Abstract

In this paper, we report the isolation method of cellulose, alpha cellulose and microcrystalline cellulose from corncorbs waste in alkaline treatment NaOH 4%,6%,8%,10%,12%,14% and 17% solution. Dewaxing, dehemiselulosa, delignifikasi and bleaching is the stage of cellulose isolation. The MCC particles were extracted by acid hydrolisis with 0.1N HCl. The 4% NaOH concentration provides the highest α-cellulose content (60%) with total yield MCC of 84.53%. SEM, FT-IR and X-ray diffraction analyzes are used to determine of the MCC. FTIR spectra showed that each MCC had -OH group, stretching of C-O on cellulose fiber I and cellulose II. C-0 bonds shows a change in rotation of glucose residue around the glycosidic bond into Cellulose II. SEM analysis showed that the concentration of 6% NaOH has a morphological structure such as cellulose standard. The 8% NaOH concentration yields a CrI value of 98%.
