Separation of ^137mBa from ¹³⁷Cs using new ion exchanger Na₂(H₂O)₄(H₃O)[Al(OH)₆Mo₆O₁₈]

Keywords: Exchanger, Synthesis, Crystal structure, Radiochemical separation

A new polyoxometalate of chemical formula, Na₂(H₂O)₄(H₃O)[Al(OH)₆Mo₆O₁₈] (1) containing Anderson type large anion has been synthesized and characterized by single-crystal X-ray structure determination and IR spectroscopic studies. The crystal of 1 is triclinic, spacegroup P−1 with cell dimensions, a=6.365(9) Å, b=10.37(1) Å, c=10.44(1) Å and α=65.41(1), β=77.18(1), γ=86.58(1) and Z=1. The compound 1 behaves as an ion exchanger and is stable in thermal, radiation and chemical environments. Radiochemical separation of the short-lived daughter ^137mBa (t_1/2=2.50 min) from its long-lived parent ¹³⁷Cs using this newly designed and synthesized ion exchanger has been developed.
