Waste-derived-lignin based hydrogel as a reusable adsorbent for efficient removal of dyes from aqueous solution

Puntos clave

• The aim is to develop a sustainable hydrogel using waste-derived lignin for effective dye removal from water.
• Fabrication of lignin/PVA hydrogel by integrating lignin with poly(vinyl alcohol)
• Evaluation of hydrogel performance as an adsorbent for dye-contaminated aqueous solutions
• Lignin-based hydrogel showed high adsorptive capacity for various dyes in wastewater
• The hydrogel is reusable, indicating potential for sustainable wastewater treatment solutions
