Enhancement of corrosion protection efficiency of mild steel by 3,5-di(4-tolyl)-4-amino-1,2,4-triazole in hydrochloric acid medium

摘要: New 3,5-disubstituted-4-amino-1,2,4-triazole derivative, namely 3,5-di(4-tolyl)-4-amino-1,2,4-triazole (4-DTAT) was synthesised and its inhibitive action against the corrosion of mild steel in 1 M HCl solution investigated at 308 K. The detailed study 4-DTAT been performed using gravimetric measurements polarisation curves method. Results show that is a good inhibitor inhibition efficiency reaches 95 % at·10 −4 M. Tafel revealed acts as mixed type inhibitor. adsorption on surface obeyed Langmuir’s isotherm. process steel/4-DTAT/hydrochloric acid system studied different temperatures (308-323 K) by means weight loss measurements.
