Abstract

Abstract It is well known that improper disposal of unused medications will pollute the environment. In addition, scientists are also looking for a corrosion inhibitor that is safe for the climate. As a result of these factors, unutilized medicinal compounds may be used as corrosion inhibitors. In a 1 M HCl solution, the effectiveness of the expired medication for treating a variety of parasitic worm infestations as an albendazole drug was assessed. Albendazole’s inhibitory efficacy increases as its concentration increases, reaching 11%. Furthermore, potentiodynamic polarization curves show that both albendazoles are mixed-type inhibitors, with anodic corrosion being the most prevalent. The findings of scanning electron microscopy surface analysis results of treated coupons match those of Tafel and OCP.
