In this study, palm shell based activated carbon (PSAC) was prepared for removal of amoxicillin in the aqueous solution. Experimental design has determined the adsorption performance of PSAC for the amoxicillin removal were greatly influence by CuFe impregnation ratio (IR). The yield of PSAC was influence by activation power and activation time. Based on the analysis of Design Expert Software, the optimum radiation power and radiation time for the preparation of PSAC were 421.34 Watt and 12.58 minute, respectively to achieve amoxicillin uptakes of 19.5443 mg/g and PSAC’s yield of 38.0025 % by using response surface methodology (RSM). The optimized PSAC shows mesoporous type of pore structures. In the batch adsorption study, the uptake of amoxicillin by the optimized PSAC was increased when the initial amoxicillin concentration and contact time increased. At pH 3, the amoxicillin percentage removal was the highest. Langmuir isotherm model was the most suitable isotherm model for the amoxicillin – PSAC adsorption system. For the kinetics study, the adsorption of amoxicillin onto PSAC followed pseudo-first-order kinetic model. Amoxicillin - PSAC adsorption system showed an endothermic nature.
