The dissolution behavior of SS 304 pipes in 2M Sulphuric acid with green inhibitor (namely neomycin) as corrosion inhibitor has been studied by Mass loss, Potentiodynamic polarization, electrochemical impedance spectroscopy and hydrogen permeation studies. All these techniques confirm that the green inhibitor retards the dissolution of steel in sulphuric acid medium.Polarization studies indicated that inhibitors are acted as mixed type. The adsorption of the compounds on SS 304 surface obeys Langmuir adsorption isotherm. © 2015, Sphinx Knowledge House. All Rights Reserved.
