چکیده انگلیسی
This research work demonstrates the use of fractional factorial experimental design technique for the novel synthesis of ordered mesoporous silica SBA-15 from the tailings slurry of a gold mine treatment plant. A two-level factorial design was employed to investigate the influence of five factors (weight ratio of NaOH/slurry, leaching time, stirring time, synthesis temperature, and synthesis time) on specific surface area (SBET). The experimental design results show that only the weight ratio of NaOH/slurry influenced SBET significantly and the obtained model predicts the SBET as a function of the weight ratio of NaOH/slurry. The experimental values were in reasonable agreement with the predicted values. It was revealed that fractional factorial design is a suitable tool for investigating the effects of large number factors simultaneously, thus reducing the number of experiments required.
