%X The corrosion inhibition effect of the Cinnamomum camphor leaves extractive for carbon steel in 10% H2SO4 solution was investigated by using potentiodynamic polarization and electrochemical impedance spectroscopy. The results showed that the Cinnamomum camphor leaves extractive had good corrosion inhibition effect for carbon steel in 10\% H2SO4 solution. The inhibition efficiency increased with increasing concentration of Cinnamomum camphor leaves extractive, and decreased with increasing temperature. The Cinnamomum camphor leaves extractive was a mixed-type inhibitor, and the adsorption of the effective corrosion inhibition component of Cinnamomum camphor leaves extractive on the carbon steel surface conformed with Langmuir adsorption isotherm equation. The addition of Cinnamomum camphor leaves extractive in sulfuric acid solution enhanced the apparent activation energy of the reaction on carbon steel, which made the corrosion inhibition effective.
