Bis-Imidazolium-Based Poly(Ionic Liquid)-Functionalized Hydrochar for Efficient Sorption of Methyl Orange and Sodium 2,4-Dichlorophenoxyacetate

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: April 2, 2025

Environmentally friendly hydrochar demonstrates excellent performance in the treatment of cationic pollutants, yet its capability to address anions is limited. Cationic imidazolium ionic liquids carry a positive charge, and modification surface can increase thereby improving ability remove anions. Herein, bis-imidazolium-based poly(ionic liquid)-functionalized (BIPIL-HC) was prepared using derived from hydrothermal carbonization bamboo powder N,N'-methylene-bis(1-(3-vinylimidazolium)) chloride via free radical polymerization characterized different instruments. The behavior BIPIL-HC adsorbing methyl orange (MO) sodium 2,4-dichlorophenoxyacetate (2,4-D Na) studied by batch adsorption experiments, including effects initial concentration temperature, solution pH, contact time on adsorption, regeneration experiments. kinetics isotherms conformed pseudo-second-order Langmuir models. capacity for MO 2,4-D Na reached 554.91 565.50 mg·g-1, respectively. also effective removing under diverse pH values highly reusable. Mechanism analysis shows that hydrogen bonding, ion exchange, electrostatic, π-π interactions promote two pollutants BIPIL-HC. Particularly, group decisive capture anionic through anion exchange electrostatic interaction. These results confirm use liquid functionalization as method modifying effectively enhance wastewater, obtained promising value wastewater handling.
