Detonation nanodiamonds (ND) present a significant part of nanocarbons group, which could be produced on commercial scale by detonation of explosives in a closed chamber. Their unique properties of high surface area, low weight and radiation resistance make ND a prospective candidate for applications in sorption processes in radiochemistry. To study the influence of surface chemistry on sorption properties, apristine sample of ND was treated with acids and hydrogen. The surface chemistry of the samples was characterised by infrared spectroscopy, X-ray photoelectron spectroscopy and Boehm titration. The sorption properties of ND were tested fordifferent radionuclides. The sorption capacity of ND was shown to be higher than those of commonly used radionuclide sorbents like activated carbon and compariable to other members of nanocarbon group like graphene oxide and carbon nanotubes. The sorption properties were shown to be influenced by the presence of oxygen-containing groups on the surface of ND. This represents an opportunity to increase the sorption capacity of ND.


Part of the work on radionuclide sorption was supported by the Russian Science Foundation (project 14-13-01279). We also acknowledge the Russian Foundation for Basic Research (project 12-05-00208) for supporting Raman and IR measurements. The authors thank the M.V. Lomonosov Moscow State University Program of Development for partial support of HRTEM measurements. We are also grateful to the “Nanochemistry and nanomaterials” user facility of the Department of Chemistry of MSU for providing the XPS measurements.
