| Résumé: | Heavy metals are present in different types of industrial effluent, being responsable for environmental pollution. Biosorption by the biomass fungic is a promising alternative method to treat industrial effluents, mainly because of its low cost and high metal binding capacity. In this paper we studied the effect of treatment at different concentration NaOH of the biomass fungic on the caracteristics of the biomass (morphology of the fungic biomass), and the capacity of adsorption of chromium. The analysis of the thermodynamic, the kinetics of adsorption, the spectra of infra-red spectra and the electron micrographs of the M.E.B. watch that these treatments, although resulting in apreciable weight reduction, also enhanced their capacity adsorption for chromium, while increasing the sorption kinetics. © EuroJournals Publishing, Inc. 2006 |
