Abstract

This study attempts to extract the microcrystalline cellulose (MCC) from mangrove (Rhizophora apiculata) wood. The wood particles were hydrolyzed with 64 % sulfuric acid (H2SO4 ) consecutively at 45 °C for an h. The chemical composition of the mangrove particles were analyzed using TAPPI standards for their extractives, holocellulose, α-cellulose, and lignin contents. The morphological structure of the fiber was viewed under the scanning electron microscopy (SEM) and light microscopy. The Fourier transform infrared (FTIR) was used to see the changes of any functional group of raw particles and microcrystalline particles after acid hydrolysis. The removal of the impurities along with defibrillation were also shown in the surface of microcrystalline cellulose. The removal of lignin and other extractives during chemical extraction and acid hydrolysis can be seen by the absence of certain band in the FTIR spectra.
