Abstract

The corrosion inhibition effect of Capsella bursa-pastoris extracts (CBE) for Q235 carbon steels in 1 mol·L

-1

hydrochloric acid solutionwas studied using electrochemical methods

environmental scanning electronmicroscopy (SEM) and Ramanmicroscopy analysis. The polarization plots indicate that CBE serves as an effective

mixedtype inhibitor. Linear polarization resistance shows that increasing CBE concentration and temperature results in increased inhibition efficiency. The highest inhibition efficiency can reach 97% when adding 60 mg·L

CBE

which is better than some reported plant extracts under the similar environment. The adsorption of CBE molecules is found to obey the Langmuir adsorption isotherm. Some thermodynamic and kinetic parameters for the adsorption process

such as the adsorption equilibriumconstant (K)

free energy of adsorption (ΔG

activation energy of corrosion reaction (E

are calculated and discussed. SEM and Raman microscopy analysis also demonstrate the formation of a CBE inhibition film on the metal surface.
