In this study, ammonium phosphomolybdate (AMP) and natural zeolite microcapsules with an excellent sorption property for Cs were encapsulated in the biopolymer matrices (sodium alginate, NaALG) to look into the removal of Cs in the simulated seawater induced by an emergency accident of nuclear power facilities. The results revealed that a relatively higher distribution coefficient (Kd) of Cs for
AMP–alginates than natural zeolite. The adsorption capacity of different alginates in AMP was (0.102±0.001 m mol/g) higher than natural zeolite (0.078±0.001 m mol/g). According to column test, both AMP and natural zeolite alginates showed an excellent removal efficiency ( ≥ 90%) under a relatively higher flow rate ( > 45mL/min) in simulated seawater. According different surface, elemental and mineral experiments, there is no obvious difference in both AMP and natural zeolite alginates after adsorption of Cs by N2-BET surface area , X-ray Fluorescence (XRF), and X-ray Diffraction (XRD) analysis.
