ABSTRACT: The effect of Juniperus communis (JC) extract on the inhibition of bronze corrosion in aqueous chloride solution was studied by electrochemical polarization methods. The variation of two experimental factors such as the chloride concentration and the temperature allows us to deduce the kinetics parameters of this process (Ea = 65.7 kJ•mol–1). Thermodynamic calculations indicated that JC adsorption on bronze surface obeyed Arrhenius adsorption isotherm and was characterized by an endothermic process (ΔH* = 54.7 kJ•mol–1).
