Abstract
The inhibitive performance of N-(naphthalen-1-yl)-1-(4-pyridinyl)methanimine Schiff base on mild steel corrosion in one molar hydrochloric acid environment was investigated by utilizing weight loss techniques. N-(naphthalen-1-yl)-1-(4-pyridinyl)methanimine has significant inhibitive performance on the mild steel corrosion in the corrosive medium. The effect of immersion time (1-24 h) and temperature (303 to 333 K) on the behavior of mild steel corrosion in the absence and presence of the N-(naphthalen-1-yl)-1-(4-pyridinyl)methanimine have also been investigated. The adsorption of N-(naphthalen-1-yl)-1-(4-pyridinyl)methanimine molecules on the surface of mild steel follows Langmuir adsorption isotherm. The surface morphology of the mild steel coupon was investigated by scanning electron microscopy. The antibacterial efficiencies of N-(naphthalen-1-yl)-1-(4-pyridinyl)methanimine for gram-negative bacteria, namely Escherichia coli, and gram-positive bacteria, namely Staphylococcus aureus was studied. The antibacterial activity findings exhibited that the N-(naphthalen-1-yl)-1-(4-pyridinyl)methanimine has significant antibacterial efficiencies against tested microorganisms.
