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

A Cationic Metal–Organic Framework Consisting of Nanoscale Cages: Capture, Separation, and Luminescent Probing of Cr2O72− through a Single‐Crystal to Single‐Crystal Process
TL;DR: A 3D cationic metal-organic framework consisting of distorted octahedral and tetrahedral cages was constructed by using Ag(I) and 4,4'-bis(1,2,4-triazole) to exhibit fast exchange, high trapping capacity, and good selectivity for Cr2 O7 (2-) through single-crystal to single-Crystal transformation.

Phosphate removal from aqueous solutions using raw and activated red mud and fly ash
Yanzhong Li,Changjun Liu,Zhaokun Luan,Xianjia Peng,Chunlei Zhu,Zhao-Yang Chen,Zhongguo Zhang,Jinghua Fan,Zhiping Jia +8 more
TL;DR: The result shows that a higher efficiency of phosphate removal was acquired by the activated samples than by the raw ones, and the Langmuir model has a better correlation with the experimental data than the Freundlich model.
Cation exchange at the secondary building units of metal–organic frameworks
Carl K. Brozek,Mircea Dincă +1 more
TL;DR: In this article, the authors provide a conceptual framework for approaching this task, addressing which SBUs undergo exchange, why certain ions replace others, how the framework influences the process, the role of the solvent, and current applications.
