摘要：

The system cellulose-water was studied by FTIR spectroscopy using KBr pellets dried and humidified for various periods of time.The spectra of the OH and CH2 vibration range were deconvoluted.The intensity of the various bands is influenced by water in varying degrees. The band positions, however, remain constant except for very high water contents. Drying improves the resolution of individual bands.The results suggest that the attribution of various bands in the range 3200-3700 cm-1 to structural elements of the system cellulose-water as described in literature. be reconsidered.
