Environmentally sustainable disposal of expired albendazole medication and its role in the protection of mild steel

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.
