Characterization of Cellulose Microfibers Isolated from Rubberwood (Hevea brasiliensis)
— Cellulose microfibers were isolated by chemical treatment followed by acid hydrolysis using sulphuric acid. The chemical compositions for extractive, holocellulose, cellulose and lignin were determined. The functional group of raw particles and cellulose microfibers of rubberwood were determined...

| Summary: | — Cellulose microfibers were isolated by chemical treatment followed by acid hydrolysis using sulphuric acid. The chemical
compositions for extractive, holocellulose, cellulose and lignin were determined. The functional group of raw particles and cellulose
microfibers of rubberwood were determined using fourier transform infrared spectroscopy (FT-IR). Morphological studies were
viewed using Scanning Electron Microscopy (SEM) to investigate physical changes of the fibers after acid hydrolysis. The results
show that cellulose content was increased to 63 % from 52 % after hydrolysis was conducted to the raw particles. Particle size
distribution of cellulose microfibers falls in the range of below 100 µm. The removal of lignin and other extractives during chemical
and acid hydrolysis can be seen by the absence of certain band in the FTIR spectra. The individualization of the fibers can be seen
after hydrolysis with sulphuric acid. The removal of the surface impurities along with defibrillation were also shown in the cellulose
microfibers. |
