Characterization of Corn Cobs Hemicellulose Using Infrared Spectrophotometry

2 Characterization of Corn Cobs Hemicellulose Using Infrared Spectrophotometry 

To a weighed amount of 1 mg corn cobs hemicellulose, 200 mg of potassium bromide was added. The mixture was ground to a homogeneous form and then analyzed the vibration in the range of wave number 500-4000 cm . Infrared spectra recorded the fingerprint spectrum and the spectrum of functional groups resulting from the hemicelluloses [5]. The results can be seen in Table 8.1. 

The FT-IR spectrum of corn cob hemicellulose is shown in Fig. 8.2. Typical signals of hemicellulose at 3282, 3076, 2041, and 895 cm were clearly observed in the sample [34]. Hemicellulose
