The sorption of Sr2+ ions from aqueous solutions on magnetically modified fodder yeast (Kluyveromyces fragilis) cells and their subsequent desorption were studied. The Sr2+ sorption increased with increasing pH and reached a plateau between pH 4.0 and 7.0. The changes of temperature slightly influenced the sorption process. The Langmuir isotherm was successfully used to fit experimental data. The adsorbed Sr2+ ions can be desorbed with nitric acid.
