Abstract

The development of eco-friendly corrosion inhibitors is a subject of several investigations, especially natural polymers. Aimed at suppressing the corrosion of L80 steel in 1 mol/L hydrochloric acid (HCl), a novel natural polymer inhibitor was developed based on xanthan gum (XG) and β-Cyclodextrin (β-CD) in this work. The corrosion inhibition effect of β-cyclodextrin modified xanthan gum (β-CD-XG) on L80 steel was evaluated by electrochemical methods, and surface analysis technology. Adsorption isotherm studies, Fourier transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS) were used to explore the corrosion inhibition mechanism of β-CD-XG on L80 steel. The results suggested that β-CD-XG was classified as a mixed-type inhibitor, and mainly suppressed the anode metal dissolution by a tight adsorption film. The formation of the film was attributed to the chemisorption of –OH, –COO-, –CH2–O–, and –CH2–O–CH2– groups on the surface of L80 steel, which conformed to the Langmuir adsorption model. The experimental results illustrated that the maximum corrosion inhibition efficiency of 94.74% was acquired at 200 mg/L β-CD-XG at 293 K.
