A comparison of chemical treatment methods for the preparation of rice husk cellulosic fibers

Abstract NaOH, H2O2 and NaOH/H2O2 treatment methods were investigated to eliminate the lignin and hemicellulose distributed in the lignocellulosic matrix of rice husk. In order to prevent the decomposition of H2O2 at higher temperatures, a low temperature treatment for 4 hours has been performed. A composition analysis indicated that NaOH/H2O2 may achieve the highest concentration of α-cellulose, but had the lowest overall solid recovery rate. Both FTIR and TGA results confirmed that only the H2O2 treated rice husk contained hemicellulose residue, which could be found at the absorption peak 1740 cm-1. The TGA analysis demonstrated the NaOH/H2O2 modified rice husks presented the most uniform structure. The SEM gave a clear picture of the raw rice husks and modified rice husks.

Keywords cellulose, delignification, H2O2, kinetics, NaOH.
