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).
