| 内容記述 | Based on limited data for the removal of radioactive 99Tc by freshwater phytoplankton, it has been thought that phytoplankton are unsuitable for remediation of 99Tc contaminated waters. This work sought to verify the validity of this assumption by studying the removal of 99TcO4- by freshwater and brackish water phytoplankton. The phytoplankton used were Euglena gracilis, Chlamydomonas pulsatilla, Chlorella vulgaris, and Spirulina platensis. Each of them was incubated for 63 days, and the removal of 99Tc from solution was periodically determined. Significant removal of 99Tc was observed only for E. gracilis, and the maximum removal was 70% of the total 99Tc added. The killed cells of E. gracilis, however, removed hardly any 99Tc. When E. gracilis cells were washed with fresh culture medium, only 13% of the total 99Tc was desorbed. These results suggested that the intracellular uptake of 99Tc by E. gracilis occurred. These results are the first documented example of significant removal of 99Tc by planktonic microalgae. | |||||
