Development of the biological approach for Holmium(III), Erbium(III), and Gadolinium(III) recovery from wastewater

Abstract

The uptake of gadolinium(III) (one of the most studied REEs), holmium(III), and erbium(III) (two less well-examined elements) by the cyanobacterium Arthrospira platensis was evaluated. According to the results of the neutron activation analysis, Arthrospira. platensis demonstrated a relatively high accumulation capacity for the studied metal ions, which were in the following order: gadolinium(III) > holmium(III) > erbium(III).
