Process optimization for Zn (II) removal by activated carbon prepared from rubber seed coat using chemical activation
The purpose of this research is to obtain optimal activation conditions for activated carbon prepared from rubber seed coat (RSCAC) using response surface methodology (RSM). Central composite design (CCD) was used to determine the properties of the three preparation variables; activation temperature, activation : char impregnation ratio (IR) on RSCAC yield time and ZnClR2 R and percentage of Zn (II) removal. Based on the CCD, two quadratic models were developed for both responses. The most influential factor on each experimental design response was identified from the analysis of variance (ANOVA). The optimum conditions obtained for preparing the RSCAC were activation temperature of 797oC, activation time 1h and IR of 2.61 resulting in 22.90 % RSCAC yield and 84.12 % Zn (II) removal.
