Biosorption of Mercury (II) from Aqueous Solutions onto Fungal Biomass (original) (raw)

2012, Bioinorganic Chemistry and Applications

The biosorption of mercury (II) on 14 fungal biomasses,Aspergillus flavusI–V,Aspergillus fumigatusI-II,Helminthosporiumsp.,Cladosporiumsp.,Mucor rouxiimutant,M. rouxiiIM-80,Mucorsp 1 and 2, andCandida albicans, was studied in this work. It was found that the biomasses of the fungusM. rouxiiIM-80,M. rouxiimutant,Mucorsp1, andMucorsp 2 were very efficient removing the metal in solution, using dithizone, reaching the next percentage of removals: 95.3%, 88.7%, 80.4%, and 78.3%, respectively. The highest adsorption was obtained at pH 5.5, at 30°C after 24 hours of incubation, with 1 g/100 mL of fungal biomass.
