多孔纤维素表面聚离子液体交联结构构建与吸附性能研究
Construction of Polymeric Ionic Liquid Crosslinked Structures on Porous Cellulose and Study on Adsorption Performance
摘要
Abstract
This study developed a novel polymeric imidazolium ionic liquid-modified porous cellulose(PC@PCIL)for the removal of azo dyes from water with high efficiency.Porous cellulose substrates(PC)were prepared from cotton pulp through an alkali/urea solvent system,fol-lowing by the introduction of 3,3-([1,1-biphenyl]-4,4-diylbis(methylene))bis(1-vinyl-1H-imidazol-3-ium)chloride and 3-butyl-1-vinyl-1H-imidazol-3-ium chloride as co-monomers.Controlled living polymerization technique was employed to construct polymeric ionic liquid in-terlinked structures on the surface of PC to prepare adsorbent PC@PCIL.This adsorbent exhibited an adsorption capacity of up to 544 mg/g for congo red in water,and the adsorption process was primarily governed by a synergistic chemical adsorption mechanism involving electro-static interactions,π-π stacking,and hydrophobic effects,following the pseudo-second-order kinetic model and Freundlich isotherm model.关键词
