Abstract
The removal of phenols from aqueous solution via activated carbon adsorption is a feasible approach to diminishing the concentration of these contaminants in drinking waters. However, both the kinetics of adsorption and the extent of adsorption at equilibrium are dependent on the physical and chemical characteristics of the adsorbate, adsorbent, and experimental system. Results of laboratory scale studies conducted to delineate the effect of such parameters on the kinetics of adsorption of phenols are reported. Parameters evaluated include: hydronium ion concentration, temperature, initial adsorbate concentration, size of adsorbent, competitive adsorption, and type of adsorbate. In addition, the nature of the rate limiting step in the adsorption process of phenols is described.
