Optimum Production of Cellulose NanoCrystal from Cotton Stalk under Acidic Hydrolysis Condition

In the present study, preparation of cotton stalk (Sahel variety) as one of the common agricultural residues was studied through three stages as Soda-AQ chemical pulping, delignification and alkaline treatment, aiming for the production of cellulose nanocrystal. In order to identify the optimum cond...
