In this study, high-performance bio-adsorbent beads composed of cellulose and lignin were developed to efficiently remove carcinogenic Cr(VI) from industrial wastewater. The cellulose-lignin beads were crosslinked and grafted with polyamine to enhance surface functionality. The fabricated beads were characterized through physicochemical analyses and tested for Cr(VI) removal performance. The amine-functionalized beads exhibited a high Cr(VI) adsorption capacity of 326.8 mg/g, demonstrating significant removal efficiency. Additionally, the beads exhibited mechanical durability and recyclability, performing effectively in continuous adsorption processes. The removal of Cr(VI) was facilitated by electrostatic interactions, chelation, complexation, and reduction mechanisms. This provides an effective approach for utilizing lignocellulosic biomass to treat wastewater contaminated with toxic metal ions.
