Efficient capture of Sr2+ from acidic aqueous solution by an 18-crown-6-ether-based metal organic framework

Here, Guo et al. report a metal organic framework material (SNU-200) functionalized with an 18-crown-6-ether, whose specific binding site with an excellent affinity toward strontium leads to excellent Sr²⁺ adsorption capability under acidic conditions at low concentrations.
