biosorption

biosorption

(1) The removal of metal ions or organic compounds from a solution by microorganisms. The goal of biosorption is the removal of heavy metals from industrial waste water, purification of precious metals such as gold or silver, or removal of soil contaminants.
(2) A physicochemical process in which biomass passively binds environmental toxins.
