Biosorption of Microelements by Spirulina: Towards Technology of Mineral Feed Supplements

Figure 11

Correlation between the concentration of Na(I) ions on Spirulina sp. surface, assessed by ICP-OES and SEM-EDX analysis. Naturalna—pristine microalgae; Co, Mn, Zn—biomass enriched in Co(II), Mn(II) and Zn(II) cations, respectively; MIX—biomass enriched in metal cations in multi-component system. Values on the and axis indicate Na(I) concentration determined by ICP-OES and EDX and analytical system, respectively.
