Protective Effect of Expired Drug on Corrosion of Copper in Acidic Medium

Abstract

Researchers used weight loss methods to investigate how the influence of expired Augmentin had on the ability of copper alloy to resist corrosion when exposed to solutions of hydrochloric acid. According to the findings, Augmentin shown remarkable effectiveness as a copper alloy inhibiting agent in acidic environment. We investigated how temperature affected the effectiveness of the medicine against corrosion, and in the end, we calculated the activation and adsorption parameters based on thermodynamics. The findings of this investigation revealed a high level of congruence regardless of the methodology employed. By using the Langmuir adsorption isotherm to match experimental data, we found that inhibitor molecules adsorb onto copper surfaces via physical adsorption, as evidenced by the levels and signs of the adsorption Gibb's free energy.
