Extraction of cellulose and preparation of nanocellulose from sisal fibers
TLDR
In this article, the feasibility of extracting cellulose from sisal fiber, by means of two different procedures was carried out, including usual chemical procedures such as acid hydrolysis, chlorination, alkaline extraction, and bleaching.Abstract:
In this work a study on the feasibility of extracting cellulose from sisal fiber, by means of two different procedures was carried out. These processes included usual chemical procedures such as acid hydrolysis, chlorination, alkaline extraction, and bleaching. The final products were characterized by means of Thermogravimetric Analysis (TGA), Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Differential Scanning Calorimetry (DSC) and Scanning Electronic Microscopy (SEM). The extraction procedures that were used led to purified cellulose. Advantages and disadvantages of both procedures were also analyzed. Finally, nanocellulose was produced by the acid hydrolysis of obtained cellulose and characterized by Atomic Force Microscopy (AFM).read more

TL;DR: In this paper, a new infrared ratio, α1372 cm.−1/α2900 cm−1, is proposed for measuring crystallinity in cellulosic materials, which can be applied to both celluloses I and II and, therefore, to samples containing a mixed lattice.
