corrosion inhibition of api 5l carbon steel by nettle leaves hydroalcoholic extract in a 0.5 m h2so4 solution
نویسندگان
چکیده
in this work, electrochemical methods such as tafel polarization and electrochemical impedance spectroscopy (eis) were used to study the inhibition efficiency of nettle leaves hydroalcoholic extract as a green corrosion inhibitor of api 5l carbon steel in 0.5 m h2so4 solution. the results showed that the inhibition efficiency was increased with increasing the concentration of the extract and the maximum inhibition efficiency in the concentration of 6 g/l was 96%. the negative sign 0 δgads absorption of inhibitor on the steel surface was spontaneous and the value 0 ads δg represented the physical absorption of the inhibitor which followed the langmuir isotherm.
