| Abstract: | The adsorption and corrosion inhibition of thiourea on carbon steel in hydrochloric acid has been investigated by weight-loss method. The experimental data have been treated with adsorption theory and sekine method. The result showed that thiourea has efficiently inhibited the corrosion of iron in hydrofluoric acid solution, the adsorption rule of thiourea on the surface of iron obeyed Lanzmuir isotherm. |
