Abstract

The adsorption of benzotriazole (BTA) on commercial copper surfaces in hydrochloric (HCl) acid concentrations from 1 x 10(-3) to 5 x 10(-1) m was investigated using gravimetric measurements. BTA in bulk solution was tested in concentrations from 1 x 10(-5) to 1 x 10(-1) m at temperatures from 298 to 328 K. The adsorption mechanism is discussed using the objective function (OF) and in terms of applicability of the conventional isotherm models. The best fit was obtained using the Frumkin equation. The projected molecular area of BTA was calculated to elucidate inhibitor orientation in the adsorption process. Copyright (C) 2006 John Wiley & Sons, Ltd.
