More recently, Song et al. described a new method to extract CNCs from raw cellulose by ball mill assisted acid hydrolysis. 43 The starting material was first ground in water using a ball mill at 1300 rpm, then treated with oxalic acid. Due to the relatively weak acidity of oxalic acid, ball milling was in this case employed as a pretreatment ...
