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.

Oxidized Activated Carbon

Activated carbon made by clean coal and 25% coconut shell was selected to be modified with different concentrations’ HNO3. The productions were characterized by BET, XPS, FTIR and the moisture adsorption of performance is investigated by the DVSA-STD dynamic vapor analyzer. The results show that specific surface area of the activated carbon modified by the 10% concentration of HNO3 is improved 1.3 times than the unmodified one. By comparison the higher concentrations of HNO3 have weaker effects on the specific area of activated carbon. The water vapor adsorption capacity of activated carbon modified by HNO3 at 10% concentration is 1.5 times higher than the unmodified at room temperature at30% RH.
