This study highlights the potential use of microalgae in the process of phytoremediation in polluted aquatic solutions due to the unique cellular mechanism of uptake of different radionuclides. The kinetics of radionuclide removal from the samples was described according to the first-order kinetics and expressed by the rate constant k and calculated for each microalga at the most suitable pH. The activity of Cs-137 and Co-60 was measured in the presence of S. obliquus or C. reinhardtii and the activity of Am-241 and Pu-239 was measured in the presence of C. vulgaris. A significant decrease of activity of Cs-137 was observed using C. reinhardtii with a rate constant of 2.4 Bq min(-1) and S. obliquus after 3 h of incubation at pH 7 with rate constant of 2.5 Bq min(-1). Chlorella vulgaris was able after 3 h of incubation to remove Am-241 and Pu-239 up to 90 and 70% in aquatic solutions at pH 1.7 and pH 1.5, with rate constants of 4.4 mBq min(-1) and 2.8 x 10(-2) mBq min(-1), respectively.
