Abstract :
Some triazole derivatives (4-amino-5-mercapto-3-methyl 1,2,4-triazole (AMMT), 4-amino-5-mercapto-3-ethyl 1,2,4-triazole (AMET) and 4-
amino-5-mercapto-3-propyl 1,2,4-triazole (AMPT)) have been evaluated as new corrosion inhibitors for the corrosion of muntz alloy (60Cu–40Zn)
in acidic and neutral solutions. The adsorption of these compounds has been tested thermodynamically which was found to be of a physisorption
mode. Furthermore, some activation thermodynamic parameters such as DH*, DS* and DG* of activation have been estimated. In addition, a trial to
find a quantitative relationship between the inhibition efficiency and the electronic properties of the inhibitor molecules was carried out
