Effect of preparation conditions of activated carbon prepared from rice husk by CO2 activation for removal of Cu (II) from aqueous solution
The optimal conditions for preparation of rice huskbased activated carbon (RHAC) for the removal of Cu (II) from aqueous solutions were investigated using central composite design (CCD). Based on the CCD, a two-factor-interaction (2FI) and a quadratic models were respectively developed for RHAC yield and percentage of Cu (II) removal. The significant factors on each experimental design response were identified from the analysis of variance (ANOVA). The optimum conditions obtained for preparing RHAC were obtained by using 737o C and 1.82 h for activation temperature and activation time respectively which resulted in 30.22 % of RHAC yield and 11.70 % of Cu (II) removal.

The optimum conditions obtained for preparing RHAC were obtained by using 737o C and 1.82 h for activation temperature and activation time respectively which resulted in 30.22 % of RHAC yield and 11.70 % of Cu (II) removal.
