The title of the article was 《A zinc metal-organic framework for concurrent adsorption and detection of uranium》.Application of 64479-78-3 The author mentioned the following in the article:
Uranium is one of the principal raw materials in the nuclear industry, but if released into the natural environment, it also poses latent health risks to mankind. Therefore, there is an urgent need to develop a strategy that can concurrently detect and adsorb uranium to realize the sustainable development of nuclear power and protect the environment. In this work, a fluorescent zinc-based metal-organic framework (HNU-50) was designed and synthesized for the effective detection and extraction of U(VI). The amide groups on N-pyridin-4-ylpyridine-4-carboxamide ligands and two uncoordinated carboxyl oxygen atoms on pyromellitic acid ligands in HNU-50 provide potential uranium-binding sites. Consequently, HNU-50 is competent of selectively and efficiently catching uranyl ions, achieving an optimum adsorption capacity of 632 mg/g. Addnl., the adsorption of U(VI) results in fluorescence quenching of HNU-50, thus allowing sensitive and selective detection of U(VI) by fluorescence change. Note that HNU-50 exhibits a considerably low detection limit of 1.2 x 10-8 M for U(VI) in aqueous solution, which is below the World Health Organization maximum pollution standards for potable water (6.3 x 10-8 M). A zinc MOF was successfully constructed by the connection between Zn(II), NPYC, and PMA ligands, which can be used to concurrently detect and adsorb uranium in aqueous solution In addition to this study using N-(Pyridin-4-yl)isonicotinamide, there are many other studies that have used N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3Application of 64479-78-3) was used in this study.
N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3) belongs to amides.Application of 64479-78-3Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis.
