Abstract
The uptake of uranium by Chlorella regularis was examined by using the solution con-taining uranium only for the first step of approach to the recovery of uranium from the aqueous systems. The uptake of uranium by C. regularis was very rapid, and was not so affected by light, temperature, and treatments with metabolic inhibitors. Eighty one percent of uranium taken up in the living cells was released by washing with EDTA solution. Seventy five percent of uranium taken up in both the living and the scalded cells was distributed in the 26, 000×g precipitate of the cell homogenate. These results suggested that the uptake of uranium by C. regularis depended upon the physical adsorption on the cell surface, but not upon the biological activity, and that uranium in the algal cells was coupled with the ligands, which was able to be easily substituted with EDTA.
