Preparation and Characterization of the Lignocellulose Aerogel

The cellulose which is the extraction from Ochroma lagopus wood was dissolved in alkali system. With the BIS as crosslinker, wood cellulosic aerogels was prepared with high porosity and absorption rate. At last, the structure and properties were characterized using SEM, FT-IR, and absorption features. Cellulosic aerogels possessed a high bleaching ability to the discolor. The corresponding parameters were with 10 hours, 25 °C, and initial concentration of methylene blue 2.4×10 -4 g/L, respectively. The quality of adsorption material 16 mg.
