  Abstract

This study, which has been addressed to the treatment of natural cellulosic fbers, aimed to investigate some properties of cattail, babassu coconut husk, Barú coconut husk, Brazil Nutshell husk, soybean pod, and peanut pod fbers, with alkaline/ hydrogen peroxide. The fbers before and after the treatment were characterized by determination of the cellulose and lignin content as determined by scanning electron microscopy, color parameters, FTIR, X-ray difraction, and thermal properties. As a result, the treatment has been efective in the partial removal of amorphous non-cellulosic polysaccharides, consequently increasing the availability of crystalline cellulose. The FTIR showed a reduction of the bands referring to lignin, the XRD indicated an increase in the crystallinity index, and the SEM analysis showed that the surface of the treated fbers became less rough and more homogeneous when compared with untreated fbers and that the thermal stability of the treated fbers had increased.
