Developing efficient and recyclable iodine adsorbents is crucial for addressing radioactive pollution. An imidazole cation-bridged pillar[5]arene polymer (P5–P5I) was synthesized via a salt formation reaction. P5–P5I exhibited high vapor capture capacity of 2130.0 mg/g maximum adsorption 1935.3 942.4 I2 I3– in solution, respectively. The kinetics on aqueous solution followed pseudo-second-order kinetic model, reaching equilibrium within few minutes. demonstrated the ability to selectively presence competing anions (10–1000-fold), removing over 97.1% from various environments. Meanwhile, under extreme conditions (strong acids, strong bases, temperature), still has superior performance cycling I3–. Molecular modeling revealed that could synergistically enhance through multiple weak interactions, including host–guest, C–H···I hydrogen bond, electrostatic interactions. This study indicates promising applications rapid uptake media.

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.
