This study investigates the potential use of agricultural waste corncob (C) that available in Malaysia, as the precursor for the preparation of activated carbon which can be applied for the removal of heavy metal, which is Cu(II) from aqueous solution. The experimental design results revealed that CO2 activation temperature, CO2 activation time and KOH impregnation ratio (IR) were important factors influencing the activated carbons yields and adsorption performance for Cu(II). The optimum conditions obtained for preparing the activated carbons from the selected precursors for CO2 activation temperature, CO2 activation time and IR were 797°C, 3.0 h and 3.5 respectively. © 2016 Author(s).
