Study finds Chlorella can Eliminate Radioactive Materials

Chlorella vulgaris


New study has found that Chlorella vulgaris has the ability to eliminate the radioactive element Strontium (Sr) through photosynthetic process.

The study was conducted by a research team led by Dr. Lee Seung-yeop from Korea Atomic Energy Research Institute (KAERI), Jung Kwang-hwan, Professor of the Department of Life Science at Sogang University and Lee Seung-yop, Professor of Department of Mechanical Engineering at Sogang University.

The research team found that when microalgae like Chlorella vulgaris photosynthesize, they facilitate the combination of CO32- and Sr2+ in the water to generate a large amount of SrCO3. They also found that the radioactivity  of Sr decreases by more than 90% when turned into a carbonate mineral, thus proving that the microalgae is effective in removing radioactive Sr.

Thus, the new technique using microalgae is expected to make it possible to treat contaminated water in a more affordable and eco-friendly manner.
