Corrosion Inhibition of Aluminum in Hcl Acid Medium by Ketoprofen Expired Drug

Abstract

In 0.5M HCL acid medium, expired ketoprofen was tested using chemical, electrochemical, and FESEM techniques at various concentrations and temperatures as an aluminum corrosion inhibitor. The outcome shows that when inhibitor concentration rises, so does inhibition effectiveness. Electrochemical According to studies, expired medication functions as a mixed sort of inhibitor. The findings demonstrate that inhibition occurs. The corrosion process's mechanism is changed by the inhibitor's adsorption on the metal surface. The According to Langmuir's adsorption isotherm, ketoprofen is absorbed. Temperature-related variables they were deliberate and calculated. The information gathered using the investigated strategies is highly congruent with Verify the efficacy of employing expired ketoprofen drugs as powerful HCL corrosion inhibitors for aluminum.
