Figure 5
FTIR spectra in the mid-infrared region of the studied polysaccharide materials (black line: cellulose, gray line: Arabic gum) using different analysis modes. From top to bottom: total reflection mode before the KKT correction, total reflection mode after the KKT correction, and transflection mode. Spectral regions of (a) 4000-375 cm−1 and (b) C-O stretching bands.
