Krishna Santosh Kumar Journal on Future Engineering and Technology 2230 – 7184 10 4 8 14 Biosorption, Mn (Manganese), Box-Behnken Design (BBD), Response Surface Methodology, Limonia Acidissima Hull Powder The objective of the present work is to find out the Influence and optimization of parameters like initial Mn (Manganese) concentration (20-100 mg/l), pH (3-5), and biomass dosage (4-6g/l) of Mn (Manganese) biosorption using the design of experiments by Box-Behnken Design (BBD) in response surface methodology. A total of 15 experiments were conducted in the present investigation towards construction of an empirical model. The optimum conditions for maximum removal of Mn (Manganese) from an aqueous solution were as follows: biosorbent dosage (5.25027 g/l), pH (4.05967) and initial Mn (Manganese) concentration (20.0653 mg/l). At the optimized condition, the maximum Mn (Manganese) removal was found to be 90.3692%. The high correlation coefficient (R^2 =0.989) between the model and the experimental data showed that that the model was able to predict the removal of Mn (Manganese) from aqueous solution using Limonia acidissima hull powder efficiently.
