- W4322750754 abstract "Expired drugs have been studied as corrosion inhibitors for metals in various environments for more than 10 years. Their similar use is due to the structure of molecules containing unsaturated bonds, aromatic rings and heteroatoms, such as O, N, S, etc., as well as conventional organic inhibitors. In his work, the inhibitory effect of expired drug Omeprazole against carbon steel corrosion in a NACE model stratum water containing 400 mg/L hydrogen sulfide was investigated. The concentration of omeprazole varied within 10…60 mg/L. The studies were carried out by gravimetry, potentiodynamic polarization and impedance spectroscopy methods. The inhibitory properties of omeprazole in the studied medium are estimated as average with a protective effect of 75…80% at the maximum concentration studied. The inhibitor causes a slowdown in both electrode reactions. The adsorption of omeprazole on the steel surface is described by the Langmuir isotherm. The calculated value of the free energy of adsorption (-29 kJ/mol) indicates the chemisorption of the inhibitor." @default.
