Optimization of medium conditions was studied through experimental design. Response surface methodology – including central composite design – was successfully applied to develop a response surface to optimize medium conditions. The most influential medium parameters were determined as initial Cu(II) concentration, pH, temperature, and adsor-bent dosage. The optimum conditions were evaluated to be 47.14 mg/L, 5.31, 38.30ºC, and 3.14 g for initial Cu(II) concentration, pH, temperature and adsorbent dosage, respectively. At these optimum points, the adsorption yield and adsorption capacity were calculated as 95.10% and 1.43 mg/g, respectively. © 2015, HARD Publishing Company.
