Abstract: [cze] [eng]
Tato diplomová práce je zaměřená na studium sorpce radionuklidu 85 Sr na zeminy odebrané v areálu jaderné elektrárny Temelín. Byla použita metoda jednorázového vsádkového experimentu, kdy k zemině byl přidán roztok radionuklidu 85 Sr o známé aktivitě. Experimenty směřovaly k vlivu pH na velikosti sorpce a vliv doby styku směsi na sorpci. Při experimentu s hodnotou pH, která byla nejblíže pH podzemní vody z JE Temelín, zeminy sorbovaly v rozmezí 31 - 44 %. Při zkoumání vlivu času na sorpci se radionuklid 85 Sr sorboval velmi rychle. Pro porovnání velikosti sorpce v závislosti na čase byl vybrán čas 120 minut, při kterém byla sorpce téměř konstantní a dosahovala hodnot 40 - 48 %. Klíčová slova Radioaktivita, radionuklid 85 Sr, sorpce, jaderná elektrárna Temelín This thesis is focused on the study of sorption of radionuclide 85 Sr in soil collected in the area of a nuclear power plant Temelín. A single-batch method experiment was used when a solution of radionuclide 85 Sr of known activity was added to the soil. The experiments focussed on the influence of pH with the size of the sorption and the influence of the time of the contact of the solution with the sorption. During the experiment with the value of pH closest to the pH of underground water from the nuclear power plant Temelín, the sorption of soil was somewhere between 31 to 44 %. When the time influence on the sorption was examined, radionuclide 85 Sr was sorbed very quickly. For the comparison of the sorption size in connection with the time, for which it was chosen 120 minutes, the sorption was almost constant, reaching 40 to 48 %.
