Abstract
This study will review the research conducted on the effectiveness of modified activated carbon in removing copper, Cu (II) in the synthetic wastewater. The activated carbon (AC) was prepared by using Ceiba Pentandra seed by physical activation using microwave irradiation. The optimization condition for the AC was studied by using Central Composite Design (CCD) by considering three factors with two responses, carbon yield and percentage removal of Cu (II) respectively. The optimum condition of AC was obtained at 264 Watt, 4 minutes and 100 cm3 carbon dioxide, CO2 flow for activation power, activation time and CO2 flow respectively. A quadratic and mean model was developed for carbon yield and percentage removal of Cu (II) respectively. Batch adsorption studies were carried out by considering the effect of different initial concentration and agitation contact time. The maximum Cu (II) removal in this study was predicted as 74% by the model with the initial concentration of 2 mg/L. The obtained data was found best fits to the Langmuir Isotherm model as for the adsorption studies. As for the kinetic studies, PseudoSecond-Order having well mechanisms sorption system compared to Pseudo-First- Order. The results for both studies are based on the highest value of the coefficient of determination, R2.
