Summary:An influential subject of research is the use of lignin for effective removal of hazardous dyes from wastewater effluents utilizing green techniques. Lignin makes up to 10–25% of lignocellulosic biomass. In this study, a solvent evaporation approach was employed to construct a novel chitosan lignin membrane, which was then used to remove the methylene blue (MB) dye from water. The physicochemical, thermal, and morphological attributes were characterized by SEM, XRD, FTIR ATR, and TGA DSC. With higher lignin content in the membrane, its tensile strength was reduced. The dye was removed 95% of the time by the membrane, and the adsorption followed the Langmuir isotherm. The membranes could be recycled up to five times. [Display omitted] •Novel chitosan/lignin membrane for methylene blue dye removal.•Solution casting method used for preparation.•Satisfactory removal potential for methylene blue removal (95%) follows Langmuir isotherm.•Regenerated and reused membranes for 5 cycles.•Eco-friendly, cheap and biodegradable.
