Covalent organic frameworks (COFs) are promising adsorbents for removing heavy metal ions, and have high crystallinity, a porous structure, and conjugated stability. N-containing functional groups are known to have great affinity for uranyl ions. In this work, to explore the peculiarity of the pyridine N structure as an efficient adsorbent, we chose 2,2′-dipyridine-5,5′-diamine (Bpy) and pyridine-2,5′-diamine (Py) as the core skeletons, and 1,3,5-triformylphloroglucinol (Tp) as the linker to synthesize two crystalline and stable N-containing COFs named TpBpy and TpPy, resp., through a facile solvothermal method. Characterization results demonstrated that TpBpy and TpPy possessed regularly growing pore sizes, large sp. surface areas and relatively strong thermal resistances. The results of batch experiments showed that both COF materials were capable of the effective removal of uranyl with uptake capacities of 115.45 mg g-1 and 291.79 mg g-1, resp. In addition, d. functional theory (DFT) simulations highlighted the beneficial chelation effect of the double N structure in pyridine monomers for removing uranyl ions. Combining systematic exptl. and theor. analyses, the adsorption process and interaction mode of porous COFs and UO2+2 were revealed, to provide predictable support for the application of pyridine N-containing COFs in the field of environmental remediation.2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Product Details of 34374-88-4) was used in this study.
2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4) is a member of phloroglucinol derivatives. Regarding monomeric phloroglucinols, this group encompasses acryl phloroglucinols, phloroglucinol-terpene adducts, phloroglucinol glycosides, halogenated phloroglucinols, prenylated phloroglucinols, and cyclicroup polyketides.Product Details of 34374-88-4
