Adsorption of lead ions by mesoporous material incorporating Gemini surfactant C16-6-16 (G-MCM-41) was investigated using response surface methodology. The effect of pH, initial metal concentration and contact time was studied using Box-Behnken design (BBD). The optimal parameters for maximum adsorption capacity (81.92 mg/g) were obtained at pH 5.85, initial lead ion concentration 99.02 mg/L, and contact time 118.49 min. The effect of different variables and their interactions were assessed by analysis of variance (ANOVA). The surface and contour response plot shows the interaction of different variables and response. The experimental data fits best in the quadratic model with maximum predicted R2 value of 0.9013 and Prob > F is <0.0001 showing the model is significant.
