Abstract

The power of Creatinine as inhibitor, for metals in 1 Molar corrosive acid solution (hydrochloric acid) has been investigated utilizing a weight loss technique. Impact of temperature and thermodynamic parameters were explored. Results demonstrated that the inhibition happens through adsorption of the creatinine molecules on the surface of the metal and the efficiencies were improved with an increment in creatinine concentration and diminished at higher temperature degrees. Scanning electron microscopy was done for the metal surface to examine it. The highest occupied molecular orbital energy, lowest unoccupied molecular orbital energy and dipole moment was theoretically calculated utilizing Density Function theory.
