Abstract

KHENBLOUCHE, Abdelkader et al. Extraction and characterization of cellulose microfibers from Retama raetam stems. Polímeros [online]. 2019, vol.29, n.1, e2019011.  Epub Mar 18, 2019. ISSN 0104-1428.  http://dx.doi.org/10.1590/0104-1428.05218.

Cellulose is the most abundant renewable resource in nature, it has various industrial applications due to its promising properties. Retama raetam is a wild plant belonging to the Fabaceae family, largely abundant in arid area which makes it a good candidate for industrial utilization. In the present study, highly crystalline cellulose microfibers (77.8% CrI) were extracted from Retama Raetam stems as a novel renewable source. The samples underwent a dewaxing process, then the microfibers were extracted using 7 wt% sodium hydroxide followed by a bleaching treatment. The extracted cellulose microfibers were characterized by Scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray Diffraction and thermo-gravimetric analysis.

Keywords : cellulose; microfibers; Retama raetam; extraction; characterization.
