The development of novel biosorbent is a challenge in the age of biotechnology. Biosorbent has a higher capacity for the removal of heavy metal pollutants from industrial wastewater and is necessary as it is more efficient than traditional technologies. In this study, we have examined living biomass of Aspergillus versicolor for the removal of Fe(II) from aqueous solution and found its maximum biosorption capacity of Fe(II) was 4.44 mg/g. This biosorption process was also tested under different conditions such as contact time, pH, temperature and initial metal ion concentration in batch setup. The optimum rate of biosorption was found after 8th days of contact time at pH 5.0 and 30˚C of temperature. The Langmuir and Freundlich isotherm model was successfully applied for the Fe(II) biosorption data and their value of correlation coefficients (R2) were obtained as 0.971 and 0.981, respectively, thus both isotherm models were best fitted on the equilibrium data. |
