Immobilization Technique for Cesium and Strontium Using Crystalline Zirconium Phosphate

Immobilization Technique for Cesium and Strontium Using Crystalline Zirconium Phosphate

Investigation of the leaching resistance of radioactive Cs and Sr immobilized using crystalline proton-type zirconium phosphate (HZr2 (PO4) 3) was carried out. The leaching rate of Cs and Sr ions from a (0.3 Cs + 0.15 Sr) / HZr2 (PO4) 3 immobilized material (the amounts of immobilized Cs and Sr were...

Zusammenfassung:Investigation of the leaching resistance of radioactive Cs and Sr immobilized using crystalline proton-type zirconium phosphate (HZr2 (PO4) 3) was carried out. The leaching rate of Cs and Sr ions from a (0.3 Cs + 0.15 Sr) / HZr2 (PO4) 3 immobilized material (the amounts of immobilized Cs and Sr were approx. 30 wt% and 6 wt%) was less than 10-4 g m-2 day-1 in both sea water and 1 mol dm-3 HCl at 433 K in an autoclave.
