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

Amino acids as highly efficient modulators for single crystals of zirconium and hafnium metal–organic frameworks
Ross J. Marshall,Claire L. Hobday,Colin F. Murphie,Sarah L. Griffin,Carole A. Morrison,Stephen A. Moggach,Ross S. Forgan +6 more
TL;DR: In this paper, the synthesis of zirconium and hafnium metal-organic frameworks (MOFs) often relies on coordination modulation, the addition of competing monotopic modulators to reaction mixtures to reproducibly generate highly crystalline material.

Uptake of metal ions by a new chelating ion-exchange resin. part 1: acid dependencies of actinide ions*
E. P. Horwitz,Renato Chiarizia,Herbert Diamond,Ralph C. Gatrone,Spiro D. Alexandratos,A. Q. Trochimczuk,Darrell W. Crick +6 more
TL;DR: In this article, a chelating ion exchange resin, DiphonixTM, has been used to extract actinide ions from neutral solvents, and the results showed that it is superior to other resins in extracting actinides from very acidic solutions.

Adsorption of selenite and selenate by nanocrystalline aluminum oxide, neat and impregnated in chitosan beads.
TL;DR: The results indicate that, in order to maintain consistent removal in more realistic systems, a pre-treatment process to manage sulfate will be necessary as indicated for other adsorbents implemented for selenium adsorption in aqueous systems.

Single-electron transfer driven cyanide sensing: a new multimodal approach.
TL;DR: A new SET-driven reaction-based strategy is reported for sensing of cyanide with indicators having low LUMO levels, which exhibits regenerability and dip-stick sensing, and fabrication of an electronic sensing device for cyanide is demonstrated.

Perchlorate adsorption and desorption on activated carbon and anion exchange resin
In-Ho Yoon,Xiaoguang Meng,Chao Wang,Kyoung-Woong Kim,Sunbaek Bang,Eunyoung Choe,Lee Lippincott +6 more
TL;DR: The mechanisms of perchlorate adsorption on activated carbon (AC) and anion exchange resin (SR-7 resin) were investigated using Raman, FTIR, and zeta potential analyses, suggesting that perchlorates was associated with functional groups on AC at neutral pH through interactions stronger than electrostatic interaction.
