GRAVIMETRIC STUDIES ON THE CORROSION OF STEEL IN AN ACID ENVIRONMENT WITH A GREEN INHIBITOR

Green inhibitors are environmentally friendly substances obtained by their extraction by various methods in alcoholic or hydroalcoholic solvents, such as maceration or Soxhlet extraction. Added in small quantities, eco-inhibitors reduce or cancel metal corrosion in aqueous solutions, by forming a film that adsorbs on the metal surface. The extract's inhibitory effectiveness depends critically on the concentration of its active ingredients. In this work, the electrochemical behavior of steel in the presence of an inhibitor derived from a plant extract is evaluated using gravimetric measurements.
