Ultrafast and Highly Selective Sequestration of Radioactive Barium Ions by a Layered Thiostannate.

As a simulant of hazardous Ra, the simultaneously selective and rapid elimination of radioactive Ba ions from geothermal water is necessary but still challenging. In this paper, we demonstrated the usability of a layered thiostannate with facile synthesis and inexpensive cost, namely, KSnS (KTS-3, = 0.65-1), for the remediation of radioactive Ba in multiple conditions, including sorption isotherm, kinetics, and the influences of competitive inorganic/organic ions, pH values, and dosages.

Three Iodoargentate-Based Hybrids Decorated by Metal Complexes: Structures, Optical/Photoelectric Properties and Theoretical Studies.

So far, the development of new iodoargentate-based hybrids, especially those compounds with metal complex cations, and the understanding of their structure-activity relationships have been of vital importance but full of challenges. Herein, using the in-situ-generated metal complex cations as structural directing agents, three new iodoargentate-based hybrids, namely, [Co(phen)]AgPbI (phen = 1,10-phenanthroline; ), [Ni(5,5-dmpy)]AgI·CHCN (5,5-dmpy = 5,5-dimethyl-2,2-bipyridine; ) and [Co(5,5-dmpy)]AgI (), have been solvothermally prepared and then structurally characterized. Compound represents one new heterometallic Ag-Pb-I compound characteristic of the chain-like [AgPbI] anions.
