The present study focused on the application of response surface methodology to optimize the fabrication of activated carbon (AC) from sugarcane bagasse for adsorption of Cu2+ ion. The AC was synthesized via chemical activation with ZnCl2 as the activating agent. The central composite design based experiments were performed to assess the individual and interactive effect of influential parameters, including activation temperature, ZnCl2 impregnation ratio and activation time on the AC yield and removal of Cu2+ ion from the aqueous environment. The statistically significant, well-fitting quadratic regression models were successfully developed as confirmed by high F- and low P-values (<0.0001), high correlation coefficients and lack-of-fit tests. Accordingly, the optimum AC yield and removal efficiency of Cu2+ were predicted, respectively, as 48.8% and 92.7% which were approximate to the actual values. By applying the predicted optimal parameters, the AC shows a surprisingly high surface area of around 1,500 m2/g accompanied by large pore volume and narrow micropore size at low fabrication temperature.

Central Composite

Activated carbon（AC）were prepared from lignin by chemical activation with sodium hydroxide（NaOH）. The influence of activation temperature，activation time and impregnation ration on the BET surface areas were investigated. Based on the central composite design (CCD) and response surface methodology(RSM)，the optimized technological parameters were as follows: temperature 751°C， time 57min and impregnation ration 2.06, BET surface areas was up to 1437.20 m2/g.The adequacy of the model equation for predicting the optimum response values was verified effectively by the validation.

Significant Factors

Avocado seeds based activated carbon was prepared using chemical activation method which consisted of potassium hydroxide treatment. The main factors influencing the preparation of activated carbons at the calcination temperature, the concentration of the activating agent and the duration of calcination were investigated. One used as a mathematical model the response surface methodology to correlate the response. The significant factors identified by the analysis of variance (ANOVA) through the t-test, the Pareto diagram and the diagrams of surfaces. The optimum avocado seeds based activated carbon was obtained by using calcination temperature of 450 oC, concentration of activating agent of 0.3 mol/L and time of calcination of 3.0 h, which resulted to an avocado seed based activated carbon iodine number remove of 1142.1 mg/g and yield of 75.09 %, by mass. The best activated carbon obtained under the previous conditions and the raw biomass was characterized by Fourier transform infrared and Scanning Electronic Microscope.

The main point of this study is to investigate the optimal conditions for preparation of activated carbon from wood sawdust (ACWSD) for removal of hydrogen sulfide (H2S) from wastewater. The response surface methodology (RSM) was employed to prepare the ACWSD by chemical activation with potassium hydroxide (KOH). The threepreparation  variables impact of activation temperature (724 – 1000 °C), KOH: precursor (wt%) impregnation ratio (IR) (2:1 – 4:1) and activation time (60 – 120 min) on removal efficiency (RE, %) of H2S and activated carbon yield (ACY, %) were investigated. The preparation parameters were correlated by developing a quadratic model depend on the central composite design (CCD) to the two responses. The analysis of variance (ANOVA) was identified the most influential variable on each experimental design responses. The results showed that the temperature of 854 °C, chemical impregnation ratio of 2.95 wt% and activation time of 80 min were the optimum conditions for preparation of ACWSD with responses of RE and ACY of 72.88 % and 31.89 %, respectively. It is concluded that the ACWSD was appeared to be a favorable substance for removal of dissolved H2S from synthetic wastewater.
