Abstract

This study examined the influence of phosphorus addition on the corrosion resistance of carbon steel for a flue gas desulJurization (FGD) system using electrochemical methods, such as potentiodynamic polarization tests and electrochemical impedance spectroscopy (EIS) in 10 wt% sulfuric acid (H ₂SO₄) solution at room temperature. The potentiodynamic measurements indicated that the addition of phosphorus increased the cathodic hydrogen evolution reaction. X-ray photoelectron spectroscopy (XRS) analyses of the corroded surfaces after the immersion testing indicated that the oxidized product of phosphorus-containing steel was composed mainly of iron(II) sulfate (FeSO₄), iron(III) sulfate (Fe₂(SO₄) ₃), and iron(III) phosphate (FePO₄). However, these products seem to have no protective property. The experimental results confirmed that phosphorus has a deleterious effect on the corrosion resistance of carban steels in H₂SO₄ solution as a result of the higher hydrogen activity.
