abstract

• The biosorption of arsenic (V) on nine chemically modified biomasses (with iron oxide coated) of mycelia fungi: Aspergillus flavus III, IV and V, Aspergillus fumigatus I–II, Paecilomyces sp., Cladosporium sp., Mucor sp-1 and 2 was studied in this work. This study provides evidence that the biomasses of the fungi A. flavus, IV, III and V, Paecilomyces sp., and A. fumigatus I were very efficient at removing 1 mg/L of the metal in solution, using atomic absorption spectroscopy (AAS), achieving the following percentage of removals: 97.1, 92.3, 90.3, 89.0, and 83.4%25, respectively. The results of adsorption were obtained at pH 6.0, 30 °C after 24 h of incubation, with 1 g/100 mL of fungal biomass. These results suggest the excellent potential of almost all isolated strains for bioremediation and removal of metals from contaminated sites. © 2017, Springer-Verlag GmbH Germany.
