Corrosion inhibitors are widely used for the protection of metal surfaces against corrosion. In many cases, the highly efficient inhibitors are very toxic and, therefore, are a high risk to health and to the environment. There is a great need for new, low cost, environmentally safe, high performance corrosion inhibitors. The main aim of this study is to examine a new class of natural corrosion inhibitors. Hence an evaluation of the effective performance of acid extracts of poultry waste (Hen feather) on the corrosion inhibition of MS in 0.5M H2SO4 at ambient temperature was made. Conventional weight loss and electrochemical measurement techniques were used for evaluation. The maximum I.E was found to be 95.5% for a period of 6 hours with 0.5% concentration of the hen feather extract. Experimental results were fitted to Langmuir adsorption isotherm. Electrochemical studies confirm the inhibitive nature of the hen feather extract and also the mixed nature of the inhibitor.
