Abstract
The sorption properties of carbon nanomaterials with different contents of the fraction of detonation nanodiamonds (DND) with respect to 238U and 232Th radionuclides were studied. The rates of U and Th adsorption-desorption in aqueous media were established. The correlation relationships between the parameters of the surface structure of samples and their sorption ability were determined. The sorption material with a maximally high DND content was found to have the highest irreversible U and Th adsorption rates.
