abstract = "Corrosion, although a natural process, presents a costly problem with the possibly dangerous
outcome. Mild steel, which is an alloy used in many industrial applications, manifests poor
corrosion resistance when in contact with corrosive environments and even more so in presence
of chloride ions. This is a particularly important problem in a variety of industrial applications
related to oil and gas processing such as pipeline cleaning pipeline/acid descaling, and oil well
acidizing, where the use of mineral acids (commonly hydrochloric acid) is necessary for
achieving satisfying productivity levels. The most practical method to combat the corrosion issue
is the use of corrosion inhibitors. Organic inhibitors with functional groups such as –OH, –
COOH, NH2, etc, when added in small concentrations to a corrosive solution, can lower the
corrosion rate very efficiently, especially in acidic media. Being that they are also inexpensive,
these organic inhibitors are successfully used for corrosion prevention. A great variety of
organic inhibitors has opened a door to environmentally friendly corrosion inhibition. One of
the environmentally friendly organic compounds are amino acids. They are non-toxic
biomolecules completely soluble in aqueous media and are produced with high purity and at low
cost which makes them a great candidate for a safe corrosion inhibitor. The application of amino
acids and their derivatives against corrosion of iron and its alloys has been investigated so far.
Amino acid based corrosion inhibitor was synthesized by condensing formaldehyde, glyoxal, and
β-alanine, and characterized using FTIR and NMR spectroscopic methods. Imidazolium
zwitterion has been investigated as a corrosion inhibitor on mild steel in 1 M HCl solution using
electrochemical methods: electrochemical impedance (EIS) and linear polarization resistance
(LPR). Different concentrations of inhibitor were used to find the best efficiency. This compound
gave a maximum inhibition efficiency of 74.3 % at 10.7 ppm. The adsorption of inhibitor on mild
steel surface followed the Langmuir adsorption isotherm. Furthermore, electrochemical
measurement results demonstrated that inhibitors act as mixed-type inhibitors (anodic and
cathodic).",
