Abstract
Dissolution behaviour of Cu-Zn alloy in 1.0 N hydrochloric acid containing ethanolic extract of Pandanus amaryllifolius leaves has been investigated by mass loss measurements at various exposure time and temperature. The inhibition efficiency increased with increase of inhibitor concentration but decreased with rise in temperature. The values of activation energy (Ea), heat of adsorption (Qads) and free energy of adsorption (∆Gads) is support that the adsorption is spontaneous, exothermic and physisorption. Inhibitor obeys both Langmuir and Temkin adsorption isotherms. The corrosion product has been analysed by using UV, FT-IR, XRD, and SEM-EDX spectroscopic techniques.
