Natural Non Toxic Green Inhibitors of Murraya Koenigii, Withania Somnifera and Glycyrrhiza Glabra Extracts for Mild Steel in 8% H2SO4

Abstract

By  means of polarization measurements UV, IR and weight loss study, it has been detected that the extract of Murraya koenigii, Withania somnifera and Glycyrrhiza glabra leaves can act as corrosion inhibitor for the sake of mild steel in 8% H₂SO₄ solution. These plants show good inhibition efficiency at particular concentrations of the acid. It is observed that plants extract act as better inhibitor on increasing their concentration. Here we have focused on the corrosion inhibition action of different plant extracts in H₂SO₄ medium.
