Absorption of CO2 in aqueous solution with Stipa tenacissima fibers

In the present work the absorption of carbon dioxide in aqueous solution with Stipa tenacissima fibers has been studied in a stirred cell at 298 K. The obtained experimental results show successful elimination of CO2(96%)through hydration of neutral aqueous CO2 molecules to HCO3− species by S. tenacissima fibers. This reactivity has been accompanied by a disorder at the surface morphology and a reduction in crystallinity % of cellulose results of the modification in hydrogen bonds. During the characterization Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) were employed to investigate the structural and morphological changes in S. tenacissima fibers.
