Notably, zeolites containing 8-membered band (8MR) showed extra-high Cs+ selectivity. Architectural evaluation utilizing X-ray diffraction proved that Cs+ with an ionic diameter of 3.6 Å was selectively coordinated within 8MR having a cavity diameter of 3.6-4.1 Å. Such unique size-selective Cs+ coordination is analogous to ion complexation by macrocyclic natural ligands (age.g., crown ethers). Divalent Sr2+ showed lowering affinity to zeolites given that Si/Al
