The corrosion inhibition of mild steel in H 2 SO 4 solution in the presence of Juniperus plant at a temperature range of 30 to 60°C was studied using chemical (HE and WL) and electrochemical (PDP and EIS) methods. The Juniperus plant acts as an inhibitor in the acid environment. The inhibition efficiency increases with increase in inhibitor concentration but decreases with an increase in temperature. The inhibitive effect of the Juniperus plant could be attributed to the presence of some compound in the plant which is adsorbed on the surface of the mild steel. The Juniperus plant was found to conform to the Frumkin adsorption isotherm and Temkin adsorption isotherm at all the concentration levels and temperature studied. The phenomenon of physical adsorption is proposed from the activation parameters obtained. Thermodynamic parameters revealed that the adsorption process is spontaneous.

“…The addition of corrosion inhibitors has been proved to be an easy and highly effective way to achieve this [1,2,3]. Organic compounds containing heteroatoms such as N, P, S or O have been used as excellent inhibitors due to their strong electron-donating ability [4,5,6]. Additionally, due to their high adsorption capacity, indazole derivatives have attracted the attention of several researchers [7,8].…”

In this work, two indazole derivatives, namely 5-aminoindazole (AIA) and 5-nitroindazole (NIA), were investigated as corrosion inhibitors for carbon steel in 1 M HCl solution by experimental and density functional theory (DFT) methods. The electrochemical results indicate that the inhibition ability follows the order of AIA > NIA, which is due to the stronger electron-donating effect of –NH2 of the AIA group than the –NO2 group of NIA. Besides, the frontier orbital theory shows that the AIA exhibits higher reaction activity than NIA, and a more negative adsorption energy for AIA was also obtained, which is consistent with the analysis of the electrochemical measurements. We draw the conclusion that the electron-donating effect makes it easier for AIA to donate electrons to iron atoms to form a stronger protective layer than NIA.
