The kinetic behavior of the adsorption of the egg albumin (EA) onto silica was studied from its alkaline aqueous solution at room temperature. Various adsorption and kinetic parameters such as the adsorption coefficient, surface coverage (θ), and rate constants for adsorption and desportion were evaluated using different rate expressions. The adsorption was found to increase on addition of H + ions to the protein solution. It was also observed that the presence of inorganic salts and cationic and anionic detergents influence both the adsorbed amount and the adsorption rate. The effect of temperature on the adsorption was also investigated. © 1996 John Wiley & Sons, Inc.
