Response surface optimization of the removal of nickel from aqueous solution by cone biomass of Pinus sylvestris.
Response surface methodology was applied to optimize the removal efficiency of Ni(II). Pinus sylvestris ovulate cones were used in this study. A 2(3) full-factorial central composite design was employed for experimental design and analysis of the results. The initial Ni(II) concentration (10-30 mg/l), pH (2.5-6.5) and biomass concentration (5-25 g/l) were the critical components of the removal optimized. The optimum pH, m (biomass concentration) and C0 (initial Ni(II) concentration) were found to be 6.17, 18.8 g/l and 11.175 mg/l, respectively. Under these conditions, removal efficiency of Ni(II) was 99.91%.
