Synthesis of high mechanical strength and excellent radiation resistance NaX zeolite microspheres via geopolymer in-situ conversion and their adsorption study of 137Cs and 90Sr

Caption

High-strength NaX zeolite microspheres with 75-150 μm particle size (GXU-NaXs) were prepared by the in-situ conversion of geopolymer technology. GXU-NaXs exhibited good dynamic adsorption effect. Density functional theory calculations revealed adsorption energies of -2.43 (Cs+) and -3.52 eV (Sr2+), while confirming the adsorption mechanism was ion exchange and chemisorption.
