AB  - The efficient, selective, and economical sorbents for the removal of Sr radionuclides are largely needed for the decontamination of effluents with high salinity. In this study, the removal of Sr was investigated using the zeolite produced from the Bayer process liquids. Based on the XRD, SEM/EDS analysis, the product was pure and highly crystalline zeolite 4A (Z4A). Removal of Sr was fast (5 min for 100% removal at 8.80 mg/L), with high maximum sorption capacity (252.5 mg/L), and independent on the initial pH in the range 3.5–9.0. Specific sorption of Sr by protonated groups on the Z4A surface was operating in addition to ion-exchange with Na ions. The selectivity of Z4A decreased in the order Sr > Ca > K > Mg > Na. 84% of Sr was separated from seawater within 5 min, at the Z4A dose of 5 g/L, while efficiency increased to 99% using the dose of 20 g/L. Desorption of radioisotope 89 Sr from seawater/Z4A solid residue was very low in deionized water (0.1–0.2%) and groundwater (0.7%) during 60 days of leaching. Z4A is a cost-effective, selective, and high-capacity medium for Sr removal, which provides high stability of retained radionuclides.

AB  - Otpuštanje 90Sr umora i okeane kao posledica testiranja nuklearnog naouružanja i akcidenata u nuklearnim objektima podstaklo je razvoj novih, jednostavnijih i bržih metoda i materijala za njegovu separaciju. Monitoring morske vode u slučaju akcidentnesituacije, kao i dekontaminacija tečnog otpada koji sadrži morsku vodu, predstavljaju izuzetno zahtevne zadatke usled složenog hemijskog sastava i visokog saliniteta matriksa. U ovom radu dat je pregled najnovijih rezultata u oblasti razvoja materijala sapotencijalom selektivnog vezivanja Sr-jona iz morske vode. Diskutovani su mehanizmi vezivanja i performanse različitih materijala sa aspekta primene u praksi i perspektivnih pravaca budućih istraživanja.
AB  - The release of 90Sr into the sea and oceans as a result of testing nuclear weapons and accidents in nuclear facilities has prompted the development of new, simpler and faster methods and materials for its separation. The monitoring of seawater in the event of an accident, as well as decontamination of liquid waste containing sea water, represent extremely demanding tasks due to the complex chemical composition and high salinity of the matrix. This paper presents an overview of the latest results in the field of material development with the potential for selective binding of Sr-ions from seawater. Mechanisms of binding and performance of different materials are discussed from the aspect of an application in practice and directions of future research.
