A promising approach in the selective separation and modification of cellulose from raw biomass under a mild alkali process was proposed. In our study ball milling was applied to wheat straw prior to alkali treatment. With ball milling ultrafine powder formed an amorphous microstructure and displayed a level of solubiliation in aqueous NaOH higher than that of general ground samples. Alkali
