Interaction of U, Np, and Pu with colloidal SiO2 particles

Interaction of U(VI), Np(V), and Pu(IV,V) ions with colloidal particles of amorphous SiO2 under the conditions simulating disposal sites of radioactive wastes and spent nuclear fuel was studied. Uranium and plutonium are quantitatively sorbed on the colloidal particles, which creates prerequisites for the colloidal transport of actinides.
