Isolation and characterizationof cellulose from rice straw and sugarcane bagasse

Cellulose from two types of lignocellulosic materials, rice straw and sugarcane bagasse were isolated by using two different methods, organosolv treatment and direct dissolution method. In organosolv treatment, solvent system consisted of a mixture of formic acid/acetic acid/water were used as these...
