Background: In the present study, three ionic liquids, namely 1-butyl-3-methylimidazolium chloride ([BMIM]Cl),
1-ethyl-3-methylimidazolium acetate ([EMIM]OAc), and 1-ethyl-3-methylimidazolium diethyl phosphate ([EMIM]DEP),
were used to partially dissolve rice husk, after which the cellulose were regenerated by the addition of water. The
aim of the investigation is to examine the implications of the ionic liquid pretreatments on rice husk composition
and structure.
