The effect of some phthalimide derivatives on corrosion behavior of copper in nitric acid

Adsorption and corrosion inhibition behavior of polyethylene glycol on α-brass alloy in nitric acid solution

“…Since these values of E * a > 40 kJ mol -1 , the metal dissolution reaction is diffusion controlled. The activation in the blocking of the active sites must be associated with a rise in the (E * a ) of α-brass corrosion in the inhibited state (51). The E * a for the corrosion of α-brass in 1 M HNO 3 was found to be 32 kJ mol −1 , which is in best agreement with the work accepted by Fouda et al (52) and others (53).…”

3-[(4-amino-2- methyl-5-pyrimidinyl) methyl]-5- (2-hydroxyethyl)-4-methyl thiazolium chloride hydrochloride as green corrosion inhibitor of copper in HNO3 solution and its adsorption characteristics

“…This result suggests that both the increase in apparent activation energy and pre-exponential factor leads to an increase in energy barrier for the corrosion of copper in HNO 3 solution. Foudal et al(31) has reported similar trend in the value of apparent activation energy for copper corrosion in HNO 3 acid solution in the presence of phthalimide derivatives.…”

On the corrosion inhibition and adsorption behaviour of some benzotriazole derivatives during copper corrosion in nitric acid solutions: a combined experimental and theoretical study

“…Several heterocyclic nitrogen containing compounds were used as corrosion inhibitors for copper in acidic media [4][5][6][7][8][9][10][11]. It reveals that most of these inhibitors were aromatic and heterocyclic compounds containing nitrogen.…”
