Response surface methodology (RSM) for optimization of cadmium ions adsorption using C16-6-16 incorporated mesoporous MCM-41

C16-6-16 incorporated mesoporous MCM-41 was investigated as an effective adsorbent for the adsorption of cadmium ions from the aqueous medium. Adsorption process was affected by different physiochemical factors such as pH, initial concentration, temperature and contact time. Optimization of experimental data was done to find out best optimal conditions using response surface methodology. Twenty nine trials were runs according to Box–Behnken design. Quadratic model was found to be best fit with maximum R2 value 0.9954 and gives the suitable relationship between the variables and response. The optimal parameters were obtained for adsorption of cadmium ions on to C16-6-16 incorporated mesoporous MCM 41. The results showed that the adsorption conditions have considerable effects on the removal of cadmium ions.
