In this study, aminated lignin (AL) was evaluated as an eco-friendly adsorbent for dye removal, addressing water pollution caused by industrialization. The introduction of amine groups enhanced the lignin's functionality, increasing its surface area compared to kraft lignin. As a result, AL selectively adsorbed Congo Red (CR) and Methyl Green (MG) under different pH conditions. In addition, the adsorption kinetics followed a pseudo-second-order model, with isotherms for CR and MG fitting the Langmuir and Freundlich equations, respectively. Notably, AL maintained high efficiency after repeated use, with adsorption mechanisms attributed to electrostatic, NH-π, and π-π interactions. These results demonstrate AL's potential in sustainable wastewater treatment.
