Optimization of the Inhibitor Efficiency of a Triazole on Corrosion of Mild Steel in 1M HCl
Y. Elkhotfi*, I. Forsal, E.M. Rakib, B. Mernari

In this work we have tried to find the best conditions to obtain maximum inhibitor efficiency of the triazole inhibitor on mild steel in a 1M HCl medium by following a response methodology. We have drawn up an experimental plan with three factors and two levels per factor in a simple way, without the use of specific software. The response (inhibitor efficiency) was evaluated by the gravimetric method. We have chosen the parameters most used in the corrosion field such as inhibitor concentration, immersion time and temperature. The results were found as the best inhibition condition of concentration of inhibitor 10-3 M, temperature of 30 °C and an immersion time of 24 h.
