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

Popis výsledku v původním jazyce

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.
