Key Points

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

Implication

Demonstrates effective dye removal in wastewater using lignin-based hydrogel, suggesting a sustainable solution.

Abstract

A sustainable lignin/PVA hydrogel has been fabricated by integrating lignin, extracted from waste-black-liquor of pulp and paper processing, with poly(vinyl alcohol) as a high-performance adsorbent for dye-contaminated wastewater treatment.
