Study A Corrosion Inhibitor Of 1-Isoquinolinyl Phenyl Ketone For Mild Steel In Acidic Medium As Hcl Acid

In this research, a study was "1-isoquinolinyl phenyl ketone" as a corrosion inhibitor with concentrations (100, 125 150 and 200 ppm) for mild steel in acidic media as HCl acid at temperatures (25, 35 and 45 C) by using the polarization and weight loss methods. The results showed that the inhibitor is good kind especially in high concentrations for inhibitor, where inhibition efficiency increased with increasing of inhibitor concentrations and temperatures, the inhibitor is mixed type revealed, presence nitrogen and oxygen atoms in structure of inhibitor its influential role in adsorption process and formation film layer on metal. Thus study effect inhibitor concentration on thermodynamics kinetic parameters E_a, ΔH, ΔS, and ΔG_ads and adsorption is chemical kind. (paper)
