Selective Adsorption Study of Bipyridine-Based Metal Coordination Polymers on Different Organic Dyes

联吡啶类金属配位聚合物(MOFs)在有机染料吸附中展示出卓越潜力。特别是联吡啶羧酸配体与钌(Ru)离子形成的MOFs,不仅应用在光催化领域,也在吸附分离中表现突出。通过合成不同结构的MOFs,并运用多种分析方法(如X-射线衍射、红外光谱、热重分析等)进行表征。研究着重于这些MOFs对甲基橙、刚果红、罗丹明B等染料的选择性吸附性能,显示出对特定染料的高效吸附和选择性。此外,探讨了金属离子和配体结构对吸附效果的影响,为开发新型吸附材料提供了重要数据。

Bipyridine metal coordination polymers(MOFs)show excellent potential in the adsorption of organic dyes,especially MOFs formed by bipyridine carboxylic acid ligands and ruthenium(Ru)ions.They are seen not only in photocatalysis,but also in adsorption separation.The MOFs with different structures are synthesized and characterized by various analytical methods(X-ray diffraction,infrared spectroscopy,thermogravimetric analysis,etc.).This study focuses on the selective adsorption performance of these MOFs for such dyes as methyl orange,Congo red,and rhodamine B.Study results show their efficient adsorption and selectivity for specific dyes.It also studies the impacts of metal ions and ligand structures on the adsorption effect,providing important data for the development of novel adsorbent materials.
