Interactions of radionuclides in solution with ions and with trace concentrations of solid phase

Original language description

Interactions of radionuclides in solutions with ions and with solid phase in trace concentrations were determined by measurement of their apparent self-diffusion coefficients. Formation of trace amounts of hydrolysis products, hydroxides of Ru(IV), Mn(IV) , Fe(III), Eu(III) and of ionic precipitate of AgI were determined from apparent self-diffusion coefficients. Transition of 85Sr2+ by ion exchange or by coprecipitation into trace amounts of Fe(III) ?hydroxide and Mn(IV)? hydrated oxide was revealed bythis method. 85Sr2+ sorbed on trace amounts of Fe(III)- hydroxide and Mn(IV)- hydrated oxides lost its individual chemical properties. This can negatively affect its separation from solution. Formation of unstable embryos of AgI trace precipitate in unsaturated solution at concentration of Ag+ 1.10-9 mol l-1 and I- 1.10-8 mol l-1 was detected by self-diffusion. Formation of trace amounts of AgI led to the decrease of sorption of I- on hydrated ferric oxide.
