Application of Destructive Neutron-Activation Analysis for Determination of Microelements in Zostera marina and Ulva lactuca

The content of micro- and macroelements was investigated in two algal species from the Bulgarian Black Sea aquatoria. The radiochemical variant of neutron-activation analysis is used for elimination of the harmful activities of the macro-components 24Na, 42K, 32P, which makes it possible to determine 56Mn, 64Cu, 76As. The quantitative composition of the elements Fc, Co, Cr, Cd, Sc, Zn, Ce, Sc, Rb, Au, Sm, As, Cu, Mn, Sb, Hg was measured.
