Dissolution of lignocellulose in ionic liquids and its recovery by nanofiltration membrane

► The dissolution kinetics of lignocellulose from a suitable source of north east India has been studied in ionic liquid. ► The rate constant for dissolution kinetics was found to be 54.79 × 10−8 cm/s. ► Recovery of ionic liquid has been studied by nanofiltration membrane. ► The permeation phenomenon has been analyzed on the basis of pore flow transport model.
