Ultrafast and Efficient Extraction of Uranium from Seawater Using an Amidoxime Appended Metal-Organic Framework.
Long Chen,Zhuanling Bai,Lin Zhu,Linjuan Zhang,Yawen Cai,Yuxiang Li,Wei Liu,Yanlong Wang,Lanhua Chen,Juan Diwu,Jianqiang Wang,Zhifang Chai,Shuao Wang +12 more
TL;DR: The origin for the superior sorption capability was probed by extended X-ray absorption fine structure (EXAFS) analysis on the uranium-sorbed sample, suggesting multiple amidoxime ligands are able to chelate uranyl(VI) ions, forming a hexagonal bipyramid coordination geometry.
Journal ArticleDOI

Effect of central metal ions of analogous metal-organic frameworks on adsorption of organoarsenic compounds from water: plausible mechanism of adsorption and water purification.
TL;DR: It is determined that a MOF such as MIL-100-Fe can be used to remove organoarsenic compounds from contaminated water because of its high adsorption capacity, rapid adsor adaptation, and ready regeneration.

Phosphate adsorption in flocculation processes of aluminium sulphate and poly-aluminium-silicate-sulphate
TL;DR: In this paper, the adsorption of mono-phosphate ions from aqueous solutions by flocs formed upon hydrolysis of alum (Al2(SO4)3) and a basic alum (poly-aluminium-silicate-sulphate [PASS]) was investigated as a function of pH (5−7), phosphate concentration (0−0.53 m m or 0−50 ppm) and coagulant concentration.

Thioether Side Chains Improve the Stability, Fluorescence, and Metal Uptake of a Metal–Organic Framework
Jun He,Ka-Kit Yee,Zhengtao Xu,Matthias Zeller,Allen D. Hunter,Stephen Sin-Yin Chui,Chi-Ming Che +6 more
TL;DR: In this article, the carboxyl-thioether combination was used for functionalizing metal-organic frameworks (MOFs) in connection with the prototypic MOF-5 system, where the thioether side chain was placed at the 2,5 positions of bdc, and the resultant molecule (L) was crystallized with Zn(II) ions into a porous, cubic network.

High-performance Hg2+ removal from ultra-low-concentration aqueous solution using both acylamide- and hydroxyl-functionalized metal–organic framework
Feng Luo,Jing Li Chen,Li Long Dang,Wei Na Zhou,Hai Lu Lin,Jian Qiang Li,Shu Juan Liu,Ming Biao Luo +7 more
TL;DR: In this article, anovel MOF material can act as a high capacity and collectable adsorbent for the removal of Hg(II) from water, especially for ultratrace Hg2+ ions in the ppb magnitude, mainly due to a combined effect from the pore walls functionalized by free-standing, accessible acylamide and hydroxyl units.
