Abstract

The authors studied the Chromium (VI) removal capacity in aqueous solution by fungal biomass of Penicillium sp., using the diphenylcarbazide method to evaluate the metal concentration. The biosorption of the metal (50 mg/L) occurs within 150 minutes, at pH of 1.0, and 28 °C. According to temperature, the highest removal was observed at 50 °C, and 60 °C, in 40 minutes, when the metal (50 mg/L) is completely adsorbed. At the analysed concentrations of Cr(VI), fungal biomass showed excellent removal capacity, besides it removes efficiently the metal in situ (63.24%, and 43% removal, seven days of incubation, 5 g of biomass, in earth and water contaminated); so it can be used to eliminate it from industrial wastewater.
