Mode of Biosorption of Chromium(III) by Spirulina Species Cells from Aqueous Solutions
The ability of commercial Spirulina species to remove chromium(III) [Cr(III)] from an aqueous environment was studied under photoautotrophic conditions. Biomass displayed high adsorptive capacity, with recorded sorption rates up to 99% at a concentration range of 0.02 to 0.18 mg chromium ions/mL of medium. Using isolated cell wall preparations, it was shown that Cr(III) is mainly sorbed onto the surface of cell walls and that the sorption capacity of the walls is enormously high. Living cells of cyanobacteria show the tendency to form multilayer sorption systems, as indicated electron microscopy.
