The inhibiting effect of four sulfa drugs compounds (eg sulfaguanidine, sulfamethazine,
sulfamethoxazole and sulfadiazine) on mild steel corrosion in 1.0 M HCl solutions were
evaluated using both galvanostatic polarization and weight loss techniques. All the
examined sulfa drug compounds reduce the corrosion of mild steel. Among the compounds
studied, sulfadiazine exhibited the best inhibition efficiency and sulfaguanidine the lowest.
The inhibition efficiency goes through a maximum for sulfaguanidine while it increases ... |
