Abstract

In this study, the interaction of pH, biomass and initial concentrations of lead (Pb) and manganese (Mn) ions in simultaneous removal of Pb and Mn were investigated using the Box-Behnken design. The results showed that there was a significant interaction between pH-Pb:Mn concentrations, pH-biomass concentration and Pb:Mn-biomass concentrations. The maximum uptake of Pb and Mn was achieved at pH 7. By increasing the Pb and Mn concentrations from 10 to 50. mg/L, the uptake capacities also increased. By increasing the biomass concentration from 0.3 to 1.5. g/L, the uptakes (g/g) of both metal ions by Bacillus cereus I6 was depleted. The precipitation of Pb and Mn on the surface of B. cereus I6 cells was confirmed by energy dispersive X-ray (EDX) transmission electron microscopy (TEM), and Fourier transform infrared (FTIR). Thus, simultaneous biosorption of Pb and Mn by isolated I6 strain can be efficiently performed under different interactions of environmental factors.
