摘要：The efficacy of an aqueous extract of the leaves and stems of Anacyclus pyrethrum L (LS-AP) as corrosion inhibitor for mild steel in 0.5 M sulphuric acid medium was carried out using the electrochemical methods. Experiments are performed by concentration of the inhibitor, temperature, synergism effect and varying immersion period. The results showed variation in inhibition performance of the inhibitor with varying concentration, temperature, iodide concentration and immersion time. Langmuir model was tested to describe the adsorption behaviour of inhibitor on the mild steel surface for all temperatures. Some thermodynamic functions of dissolution and adsorption processes were also determined
