“…6], the use of adsorption inhibitors is much encouraged due to non toxicity. Recently, drugs such as atenolol, bisoprolol and tenoxicam have been used as inhibitors to fight metal corrosion in an acid environment [7][8][9][10]. Medicines may therefore be a better choice because they are available, inexpensive and non main objective of this work is to study the behavior of piroxicam with respect to the orrosion of copper in a 1M nitric acid medium.…”

The objective of this work is to assess the inhibitory efficacy of the piroxicam molecule on copper corrosion in a 1M nitric acid medium using the mass loss technique (gravimetry). The inhibition efficiency, represented as IE (%), increases with higher concentrations and temperatures. Various adsorption isotherm models (Langmuir, El-Awady, Freundlich, and Temkin) were employed to describe the interactions between the molecule and metallic copper. The Dubinin-Radushkevich isotherm, along with the Adejo-Ekwenchi isotherm, was utilized to identify the types of adsorption. Additionally, the thermodynamic adsorption and activation functions were determined and analyzed.

Due to its massive use, the behavior of aluminum in a 1 M nitric acid solution was studied in this work; this study which is mainly based on the inhibitory properties of 2-((benzylthio)methyl)-1H-benzo[d]imidazole (2-BTM1HBI) was carried out using the mass loss technique of temperature varying from 298 to 338 K and concentration of 10-3 mM at 5 mM. The inhibitory efficiency of 2-BTM1HBI increases with the increase of the concentration and this up to 96.09% but decreases with the increase of the temperature. The study of isotherms shows that the adsorption of the molecule studied on the surface of aluminum obeys the modified Langmuir isotherm (villamil model). The thermodynamic adsorption quantities were determined and discussed. They show that the adsorption of 2-BTM1HBI is spontaneous and exothermic with an increase in disorder. Adsorption is done in two modes: physisorption and chemsorption with a predominance of physisorption. The thermodynamic quantities of activation have shown that the dissolution process is endothermic with an increase in disorder.
