Abstract

and dye sulfonate groups) plays the predominant role in adsorption, supplemented by π-π interactions with defect-rich graphene surfaces and hydrogen bonding between functional groups. This dual-function, reusable adsorbent advances lignin valorization and aligns with green chemistry principles, providing a scalable and versatile material for wastewater treatment.
