Аннотация: The nanostructured polycrystalline ZrMo2O7(OH)2(H2O)2 coating was synthesized on coal fly ash cenosphere derived microsphere glass supports via a two-step mild hydrothermal procedure resulting in a microsphere composite of a hollow core-shell structure. Sorption properties of the microsphere composite with respect to Cs+, Sr2+ and Показать полностьюNd3+ as non-radioactive imitators of 137Cs, 90Sr and actinides (III) were estimated. The nanostructured design of the coating was shown to enhance the Nd3+, Sr2+,Cs+ sorption in comparison with pure microsized ZrMo2O7(OH)2(H2O)2. Nd3+, Sr2+, Cs+ sorption distribution coefficients were determined (0.52104, 0.40103 and 0.92102 mL/g, respectively) and preferential Nd3+ sorption was explained on the basis of ZrMo2O7(OH)2(H2O)2 structure. © 2019 Elsevier Ltd.
