Adsorption Studies of Cyanide (CN) - on Alumina
Abstract
In this investigation, adsorption of cyanide on to alumina has been studied by means of batchtechnique. Percentage adsorption was determined for Alumina-Cyanide solution system as a function of (i) contact time, (ii) pH, (iii) adsorbate concentration and (iv) temperature. Adsorption data has been interpreted in terms of Freundlich and Langmuir equations. Thermodynamics parameters for the adsorption system have been determined at three different temperatures. The value of ΔHo=5.448kJ/mole and ΔGo=-7.162kJ/mole at 283K suggest that the adsorption of cyanide on Alumina is an endothermic and spontaneous process.
