Biosorption of lead (II) from aqueous solutions by three fungal biomasses

The biosorption of lead (II) on threefungal biomasses:Mucor rouxii-1, Mucor rouxii-2, and Aspergillusflavuswerestudied in this work. It was found that the biomassesof the three fungiwere very efficient removing the metal in solution, using Dithizone, reaching the next percentage of removals: 96.1%, 91.5%, and 57%, for M. rouxii-1, M. rouxii-2, and A. niger, respectively. The highest adsorption was obtained at pH 4.0-5.0, at 28°C after 24 hours of incubation, with 1 g/100 mL of fungal biomass. It is concluded that the studied biomasses, can be used for the treatment of wastewater, specifically in metal removal heavy as lead (II).
