Abstract

This study aimed to describe the adsorption of three pharmaceuticals which represents a source of environment contamination. The adsorption of three drugs: ibuprofen (IBU), naproxen (NAP) and carbamazepine (CBZ) from river water onto cuttlefish bone powder (CFPB) as adsorbent material were carried of various parameters such as contact time, the effect of pH, the varying of the concentration and the temperature. Adsorption kinetic data were modeled using the Lagergren first order and the pseudo-second order kinetic equations. The kinetic results of adsorption are described better by using the pseudo-second order model. Freundlich and DR equations provided better compatibility than Langmuir equation. The thermodynamic parameters obtained indicate that the adsorption of pharmaceuticals on the cuttlefish bone powder is a spontaneous and endothermic process
