Abstract: In this research, adsorption of cyanide onto cata- lyst synthesized with activated carbon and γ- alumina used supported and cooper has been studied by means of batch technique. Percentage adsorption was determined for this catalyst in function of pH, adsorbate concentration and temperature. Adsorption data has been interpret- ed in terms of Freundlich and Langmuir equa-tions. Thermodynamics parameters for the ad-sorption system have been determined at three different temperatures.

Keywords: Activated carbon; Alumina; Cyanide; Isotherms; Thermodynamic
