Effect of potassium on stable cesium uptake by Calla palustris from aqueous solution
 Petrůvová, Nicola ; Komínková, Dana (advisor) ; Petr, Petr (referee)
The aim of the thesis was to evaluate the effect of potassium on receiving of stable cesium and evaluate the appropriateness of Marsh Calla (Calla palustris) for phytoremediation. The experiment was conducted in a green-house environment where the plants were grown in an aqueous solution. The plants were exposed then to a stable isotope of cesium (133Cs) at a concentration of 1 mM CsCl. Potassium was added to the plants in the form of potassium sulphate (K2SO4), in five different concentrations (0.5 mM, 1 mM, 2 mM, 5 mM and 10 mM). Plants were exposed for 8 days. The largest average income of cesium (9,37 %) had a plant without added potassium. The root part of the plants showed a greater cesium content than the ground part. Based on the total intake of cesium from an aqueous solution, calla marsh can be estimated as a plant usable for phytoremediation.
