- Аннотация: The possibility of removing U(VI) from aqueous solutions using layered double hydroxides of Mgand Al, which contain β-cyclodextrin (LDH-Mg-Al-CD), has been studied. It is found that LDH-Mg-Al-CD does not sorb [UO2(CO3)3]–4 (the sorption degree does not exceed 0.001% after 24-h contact betweenthe solid and liquid phases). At the same time, it is established that the application of LDH-Mg-Al-CDallows the quick and efficient cleaning of 10–2–10–3 mol/L aqueous solutions of UO2(NO3)2. For all the synthesized LDH-Mg-Al-CD, a degree of U(VI) sorption from 10–3 and 10–2 aqueous solutions of UO2(NO3)2 which is higher than 99.9% is achieved after 30 and 60 min of contact between the solid and liquid phases at V/m = 100 mL/g, respectively. The investigations of the liquid phase after 24-h contact between water and LDH-Mg-Al-CD with sorbed U(VI) revealed an almost complete lack of the U(VI) desorption into the aqueous phase.
