Abstract

In this investigation, the application of the Ceftin drug on the prevention of the corrosion of carbon steel in 3 % NaCl solution was examined through weight loss (mass loss), gasometric and atomic absorption spectroscopy techniques. The effectiveness of the Ceftin drug as corrosion inhibitor for carbon steel was proved by weight loss, gasometric and atomic absorption spectroscopy results. The increase in the Ceftin drug concentration decreases the carbon steel weight loss in the 3 % NaCl solution, which is due to the formation of invisible thick layer on the carbon steel in the 3 % NaCl solution. The increase in the contact time decreases the corrosion inhibition property of expired Ceftin drug. Gasometric studies show that, the amount of hydrogen gas evolved decreases with rise in the concentration of 3 % NaCl solution. The results of atomic absorption spectroscopy well support the weight loss (mass loss) and gasometric results.

Summary

Introduction

The carbon steel (CS) is important metal because of their wide range of applications in the several industries. This cause damage to the CS metal. Prevention of CS corrosion in the NaCl solution is very much essential. Most of the corrosion inhibitors are organic compounds which contains N, S, P and O atoms in their moieties. These elements adsorb on the metal surface in the corrosive solution and prevent the corrosion process by blocking the attack of corrosive ions on the surface of the metal. In current research selected expired Ceftin drug and studied its corrosion inhibition property on CS in 3 % NaCl solution with the aid of gasometric, weight loss and atomic absorption spectroscopy techniques
