USE OF CYANOBACTERIUM ARTHOROSPIRA PLATENSIS FOR URANIUM EXTRACTION FROM ALKALINE LAKES
In the article the effect of using A.Platensis for uranium extraction from the saline-alkali Lake Tanatar of the Kulunda Steppe was studied. The growth of A. Platensis at different salt concentrations and pH ranges close to those of Lake Tanatar was analysed. The presence of uranium in solution was found to have no effect on the growth of A. Platensis. The ability of a living organism to immobilise uranium was found to be significantly higher than dead biomass. The results of uranium desorption showed that from the biomass, once collected, uranium is optimally extracted with a 0.1 M soda solution.
