- •
The work demonstrates the pretreatment of lignocellulosic biomass from North East India in IL.
- •
Lignocelluloses were characterized by FTIR, XRD, SEM and zeta potential analysis.
- •
Role of imidazolium based ionic liquids on dissolution of lignocelluloses and their effect for regeneration of celluloses were discussed.
- •
Recovery of lignin from IL was studied and characterized the recovered product.
- •
IL was recovered by membrane and reused.
