Lignin has useful and signi cant properties such as sti ness, resistance to UV radiation, antioxidant, antimicrobial, high thermal stability, and high carbon content. Due to these properties, lignin can be used for several applications including wood adhesive and carbon-based material, and can be developed as a functional material composite. Isolation and utilization of lignin from lignocellulosic biomass o ers signi cant opportunities in various now and future industrial applications mainly for development of advanced materials. In this study, isolation and characterization of lignin from oil palm shells (OPS) was conducted. Lignin was isolated from OPS using the precipitation method with sulfuric acid and coagulation using polyaluminum chloride (PAC). The isolated lignin was identi ed using Fourier Transform Infrared (FTIR), X-ray di raction (XRD), and scanning electron microscopy (SEM). Based on the FTIR analysis …
