Metal ions biosorption from dilute aqueous solution
Biosorption, using non-living biomass (mostly suspended), is briefly reviewed in this paper as applied to toxic metal ions removal, with particular focus on the kinetics and engineering considerations of the process. Several diverse kinetic models were successful in fitting the experimental data. Evidence was provided that the metal biosorption (on Aeromonas caviae biomass) is a complex process. The examination of satisfactory and innovative wastewater treatment techniques has become an important requirement nowadays, and one of the significant subjects under investigation is the effective recycling of water and for precious or strategic metals themselves.
