The increasing human population and pharmaceutical industry expansion lead to the increasing drug consumption. According to this, several studies found pharmaceutical compounds in various environmental components. One of the most abundant pharmaceuticals found is carbamazepine. Long term consumption of water containing pharmaceuticals can harm human body, so it needs to be removed. One of the pharmaceutical removal techniques is adsorption with clay adsorbent, such as montmorillonite clay. Montmorillonite has a good adsorption ability due to its characteristics. This study was conducted to determine the variables that affect adsorption and the optimum conditions for adsorption using montmorillonite clay. The adsorption experiment was modeled and analyzed using Design Expert 13 through surface response methodology-box Behnken design. Adsorption was modeled with three main factors; concentration of carbamazepine, pH, and clay dose. The quadratic polynomial was chosen for explaining adsorption. The study show that optimum percent removal of carbamazepine occurred at pH < 7, with concentration of carbamazepine and clay dose at higher level. The study showed that the optimum conditions for adsorption of carbamazepine occurred when the concentration of the waste carbamazepine was 9.65 mg/l, pH was 5.8 and the clay dose was 19.75 g/l. The optimum conditions were acidic (3), neutral (7) and alkaline (11) when the concentration of carbamazepine was 9.77 mg/l, 10 mg/l, 10 mg/l, and the clay dose was 18.19 g/l. l, 20 g/l, 20 g/l.
