Yildiz, Resit published the artcileEvaluation of corrosion inhibition of mild steel in 0.1 M HCl by 4-amino-3-hydroxynaphthalene-1-sulfonic acid, HPLC of Formula: 116-63-2, the publication is Corrosion Science (2014), 215-221, database is CAplus.
The corrosion behavior of 4-amino-3-hydroxynaphthalene-1-sulfonic acid (4A3H1S) in 0.1 M HCl on mild steel (MS) was measured by electrochem. impedance spectroscopy (EIS), linear polarization resistance (LPR) and potentiodynamic measurements at various concentrations The surface morphol. of the MS was examined by SEM both in the absence of an inhibitor and in the presence of a 10 mM 4A3H1S-containing corrosive medium. The inhibition mechanism was determined by the potential of the zero charge (Epzc) measurement at the solution-metal interface. The adsorption of 4A3H1S on the surface of MS obeyed the isotherm of Langmuir adsorption.
