摘要：New 3,5-disubstituted-4-amino-1,2,4-triazole derivative, namely 3,5-bis(3,4-dimethoxyphenyl)-4-amino-1,2,4-triazole (3,4- MAT) was synthesised and its inhibitive action against the corrosion of mild steel in 1 M HCl solution was investigated at 308 K. The detailed study of 3,4-MAT was been performed using gravimetric measurements and polarisation curves method. Results show that 3,4-MAT is a good inhibitor and its inhibition efficiency reaches 98 % at· 10 .3 M. Tafel polarisation study revealed that 3,4-MAT acts as a mixed type inhibitor. The inhibitor adsorption process in mild steel/3,4-MAT /hydrochloric acid system was studied at different temperatures (308-323 K) by means of weight loss measurements. The adsorption of 3,4- MAT on steel surface obeyed Langmuir's adsorption isotherm. The kinetic and thermodynamic parameters for mild steel corrosion and inhibitor adsorption, respectively, were determined and discussed
