The stronger coordination ability of mercury ions with organic ligands than the metal ions in metal organic framework(MOFs) provides an accessible way to separate mercury ions from solution using specific MOFs. In this study, a Co-based MOF(ZIF-67, Co(mIM)) was synthesized. It did not introduce specific functional groups, such as-SH and-NH, into its structure through complicated steps. It separate Hgfrom wastewater with a new strategy, which utilized the stronger coordination ability of Hgwith the nitrogen atom on the imidazole ring of the organic ligand than the Coions. Hgreplaced Conodes from ZIF-67 and formed a more stable precipitate with m IM. The experimental results showed that this new strategy was efficient. ZIF-67 exhibited Hgadsorption capacity of 1740 mg/g, much higher than the known MOFs sorbents. m IMs is the reaction center and ZIF-67 can improve its utilization. The sample color faded from purple to white due to the loss of cobalt ion. It is a great feature of ZIF-67 that allows users to judge whether the sorbent is deactivated intuitively. ZIF-67 can be sustainable recycled by adding organic ligands to the solution after treatment due to its simple synthesis method at room temperature. It’s a high-efficient and sustainable sorbent for Hgseparation from wastewater.

Ceramics International 2025年

作者： Xu, Renze Wang, Zhen State Key Laboratory of Mesoscience and Engineering Institute of Process Engineering Chinese Academy of Sciences Beijing100190 China School of Chemical Engineering University of Chinese Academy of Sciences Beijing101408 China

The influences of FeOx on viscosities, structures and phase transformation of CaO-Al2O3-SiO2-MgO-BaO-(1-7 wt%)FeOx bosh slags were researched. The slag viscosity and the break point temperature gradually reduced with adding FeOx from 1 wt% to 7 wt%. Raman spectra and XPS results indicated that higher FeOx content in bosh slags could facilitate to form uncomplicated silicate units, which was conducive to decreasing the slag polymerization degree and the viscosity. From the XRD results of the slag at different temperatures, merwinite and melilite phase was precipitated and coexisted in bosh slags when the temperature was lower than the break point temperature, and the species of the crystalline solids was not changed with the addition of FeOx. Finally, the relationship among the viscosity, structure and crystal phase was further discussed. At high temperature, the bosh slag viscosity was mainly influenced by the microstructure. With the temperature decreasing and the formation of crystalline phases, the viscosity was simultaneously affected by the structure and solid phase. When the temperature was further reduced, a lot of crystals were crystallized from the molten slag and the viscosity was significantly determined by the size and morphology of the solid crystal. The comprehensive influences of the microstructure and macroscopic phase increased the viscosity with reducing the temperature. © 2025 Elsevier Ltd and Techna Group S.r.l.
