“…Another set of additives that have been shown to enhance the inhibition properties of EDTA is hydroxylamine sulfate and Fe 2+ . 86 Finally, the inhibiting properties of EDTA on steel surfaces can be strengthened through the addition of Fe 3+ ions to the solution. 81 A magnesium hydroxide-EDTA coating reduced the corrosion rate of bare AZ31 Mg alloys by one or two orders of magnitude.…”

“…In experiments of mass loss measurements and electrochemical tests, it was found that the increase in the EDTA concentration decreases the inhibition efficiency of some inhibitors (Umamathi et al, 2008). Nevertheless, some researchers have reported the use of EDTA compounds, like the EDTA-Hydroxylamine Sulfate-Fe 2+ as corrosion inhibitors for stainless steel (Capobianco et al, 1994). This controversial situation is still unsolved.…”

The use of chelating agents in the oil well stimulation processes has been proposed as an alternative to the acid treatment when the formations damage do not allow the usage of strong chemical attack. However, this procedure can arouse the corrosion of the steel used in the infrastructure of the oil production. In this study, the corrosion kinetics of the P-110 steel in ethylenediaminetetraacetic acid (EDTA)based fluids is assessed under different conditions of evaluation. Linear polarization was performed in different hydrodynamic regimes and at different temperatures, in order to evaluate the kinetic of steel corrosion. The working electrolyte solution comprises 10% disodium EDTA and 20% tetrasodium EDTA. The increase of temperature from 25 to 80°C in both electrolytes increments the corrosion rate of steel in at least one order of magnitude; particularly in EDTA-Na2 solutions. Corrosion rates of 0.29x10 1 and 1.67x10 2 mm.y -1 were measured at 25 and 80°C, respectively. The hydrodynamic regime plays an important role in the corrosion of steel only in the disodium solution, where corrosion rates were increased at higher rotation speeds of the electrode. The cathodic depolarization effect is more important in the EDTA-Na2 than in the EDTA-Na 4 solution, making it more corrosive.
