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

Abstract

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.
