Abstract

Objective: Aluminum (Al) corrosion in the NaCl solution is an example of dissolution in the neutral medium. The ongoing corrosion research efforts to produce the eco-friendly corrosion inhibitors to protect the aluminum metal from the corrosive solution.


Methods: Herein, mass loss and atomic absorption spectroscopy (AAS) techniques were conducted to explain the adsorption property of expired Fluoxymesterone drug on the Al surface in the 3 % NaCl solution.


Results: All results show that the expired Fluoxymesterone drug molecules generate a stable invisible layer through adsorption mechanism on the electrode surface. The corrosion inhibition behavior mainly depends on the concentration of the expired Fluoxymesterone drug and contact time at 313 K.


Conclusion: The corrosion inhibition property is due to adsorption of electron-rich molecules on the Al surface in 3 % NaCl solution.

Keywords: Aluminum, Mass loss, Expired Fluoxymesterone drug, Contact time, Atomic absorption spectroscopy
