The present paper deals with sorption properties of alginates of differ origin in relation to radionuclides Mn⁵⁴, Fe⁵⁵, Co⁵⁷ end Sr⁹⁰. The Ca alginate obtained from the Mediterranean Sea brown alga Cystoseira corniculata was found to accumulate Mn⁵⁴, Fe⁵⁵, Co⁵⁷ and Sr⁹⁰ to the concentration factors (c.f.) 122, 663, 137, 1510 and 519 units. The same radionuclides c.f. for the Ca alginate extracted from the Black Sea brown alga Cystoseira barbata are equal to 101, 245, 63 and 182 respectively. Alginic acid obtained from the Na alginate at the Arkhangelsk algal enterprises sorbs radionuclides of Mn, Fe, Co and Sr only in insignificant quantity. Their c.f. are 5, 77, 11 and 14. Difference in the sorption properties of alginates of different origin in sea water might be due to their different chemical composition.
