Optimization of the corrosion inhibition performance of novel oxadiazole thione-based Schiff base for mild steel in HCl media using Doehlert experimental design

Corrosion Inhibition of Carbon Steel by Some Schiff Base Compounds in HCl and H2SO4 Solutions

“…[15] Consequently, Schiff bases have emerged as promising candidates for corrosion inhibitors due to their excellent adsorption and film-forming properties in recent years. [16][17][18][19][20][21][22][23][24][25] In particular, several Schiff bases have been identified as effective corrosion inhibitors for mild steel, [26][27][28][29][30][31][32] aluminum, [33,34] and copper [35,36] in media containing HCl [26,37] and H 2 SO 4 . [30,31] For example recently Betti et al investigated the corrosion protection of a novel Schiff base, 3-((5-mercapto-1,3,4-thiadiazol-2-yl) imino)indolin-2-one (MTIO), and achieved 96.9 % inhibition efficiency for mild steel in HCl solution.…”
