The Biosorption Process
An Innovation in Reclamation of Toxic Metals
Abstract The ability of microorganisms to remove metal ions from dilute aqueous solutions is a widely studied phenomenon. Numerous applications of biosorption, mainly in laboratory or in pilot-scale, but recently also industrially, make often use of non-living biomass, which does not require supply of nutrients and can be exposed to environments of high toxicity without problems. It was observed also that in most cases the non-living biomass showed greater binding capacities for cadmium, than the living one. Selected experimental laboratory batch results, using actinomycetes, fungi and (dried and sterilized) activated sludge as biosorbents of metals will be presented in the following. An insight of cadmium (a priority pollutant) sorption was attempted and among others, the known Langmuir isotherm was used, describing sufficiently the process. The commercial future of biosorption as a toxic metal ions reclamation process, is connected with the practical solution of several engineering problems, such as the efficient separation of metal-loaded biomass.
