Abstract:
The corrosion inhibition of mild steel in seawater with the use of two Linear alkyl benzene sulfonate (LABS)-based household detergents was investigated and compared. For purposes of product right and identity protection these would hereafter be named inhibitors A and B respectively. The investigations were based on gravimetric method. The main parameters considered were effects of inhibitor concentration and time of immersion. Particular attention was given to the influence of immersion time on weight loss and corrosion rates. The investigations revealed that both inhibitors are good corrosion inhibitors, though with different magnitudes. Generally, corrosion rates and weight loss values for investigations carried out with either inhibitor A or B were less than those without inhibitors except in the case of 0.22g/l of inhibitor A. Furthermore, it was observed that inhibitor B was more efficient compared to inhibitor A probably due to the presence of sodium silicate in B. The difference in corrosion inhibition of these detergents may be closely related to their individual cleansing abilities.
