In the present paper, bioaccumulation characteristics of Vaucheria sessilis were presented. The ability of macroalga to bioaccumulate Co(II) and Mn(II) ions was investigated using scanning electron microscopy with an energy dispersive X-ray analytical system (SEM-EDX) and inductively coupled plasma optical emission spectroscopy (ICP-OES). After two weeks of the experiment, macroalga accumulated about: 71.3 mg/g of Mn(II) and 41.9 mg/g of Co(II) ions. Micrographs performed by SEM proved, that bioaccumulation occurred. Metal ions were bound on the surface and in the interior of biomass. Mappings of cations showed, that in the case of the surface of biomass (biosorption), the elements constituted aggregations. In turn, in the case of the cross section (bioaccumulation) they were evenly distributed. The ability to bioaccumulate microelement ions by Vaucheria sessilis creates opportunities for its wide application. This macroalga constitute a perspective raw material for agricultural applications, not only due to pronounced microelement accumulation capabilities but also due to the content of bioactive compounds.
