  • High SF6/N2 selectivity in a hydrothermally stable zirconium

    Sep 15, 2015 · A hydrothermally stable, zirconium-based metal–organic framework called UiO-66-Zr has been studied for its ability to separate SF 6 from SF 6 /N 2 mixtures. The ideal adsorbed solution theory (IAST)-predicted selectivities based on single-component isotherms and the dynamic breakthrough calculations for mixture conditions demonstrate that UiO-66-Zr can effectively separate SF 6 /N 2 mixtures.
