ABSTRAKT
The methods of radiochemistry, cyclic voltammetry and electron scanning microscopy were employed in experiments with Spiruiina platensis (Nordst.) Geitl. CALU-835 to determine chemical and biochemical mechanisms of biological purification of waters containing U(VI). It has been established that under the absence of ionic competition, the S. platensis culture is able to accumulate up to 90 % of UO22+ ions, which are present in the solution of UO2(NO3)2·10−1 M. The data obtained indicate the formation of large polymer conglomerates, which are connected with the external side of the cell membrane and uranyl, introduced into the system.
