Key Points

This study aims to compare the efficiency of bio-based sulfur copolymers derived from safflower and linseed oils for dye removal from wastewater.
Developed sulfur copolymers from unsaturated safflower and linseed oils.
Systematically tuned oil unsaturation and porosity induced by NaCl.
Assessed adsorption kinetics and surface properties of the copolymers.
Copolymers showed significant dye removal efficiencies with values ranging from 0.973 to 0.996.
Tuned properties enhanced adsorption kinetics and surface heterogeneity.
Demonstrated potential as biodegradable and thermally stable alternatives for wastewater remediation.

Abstract

= 0.973-0.996) for all copolymers. This work demonstrates that systematically tuning oil unsaturation and NaCl-induced porosity provides a simple, scalable strategy to design sulfur-based copolymers with programmable adsorption kinetics, surface heterogeneity, and removal efficiency, offering a sustainable, biodegradable, and thermally stable alternative for the remediation of dye-contaminated wastewater.
