Description
Summary:Today nanomaterials, including carbon ones, considered to be promising radionuclide carriers for nuclear medicine. We previously determined that nanodiamonds (NDs) have the best sorption properties in comparison to other carbon nanomaterials for the range of medical radionuclides including 90 Y. At the same time, it was shown that the surface composition of NDs does not influence sorption and desorption for this isotope. In this work the influence of aggregate sizes of NDs and ζ-potential of their surface in water solutions on their sorption and desorption is studied, using 90 Y as an example. It was determined that with the increase in aggregate sizes and decrease in ζ-potential the sorption decreases, which lets specify the mechanism of binding of 90 Y to NDs. It was shown that creation of suspension with determined sizes of particles is an important task for the future use of NDs as medical radionuclide carriers.
