Abstract The inhibitive of the mild steel corrosion in a corrosive environment by 2-(5-amino-1,3,4-thiadiazol-2-yl)-5-nitrofuran (ATFuran) has been investigated using gravimetric techniques. ATFuran as investigated corrosion inhibitor exhibited the highest inhibitive efficacy of 83.26% at the highest concentration of inhibitor of 0.005 M studied, for the immersion time of 5 h and a temperature of 30 °C from the gravimetric result. Moreover, the inhibition efficiency was increased with increasing ATFuran concentration and decreasing with exposure time or solution temperature. A reduction in inhibition efficacy with temperature increase is implied to the mechanism of physisorption and may be imputed to increase in the solubility of the precipitated ATFuran molecules on the surface of metal. The number of adsorbed molecules on the surface of the metal decreases regarding the temperature increases which resulted in a deficiency in inhibitive performance. The kinetic studies indicate that the adsorption of tested inhibitor on the metal surface both physical and chemical adsorption. ATFuran obeys the Langmuir adsorption isotherm equation.
