| Popis: | The corrosion inhibition effect of citrus sinensis belonging to Rutaceae family has been analyzed on the low carbon steel corrosion in 0.5 M H2SO4 by using weight reduction estimations and electrochemical measurements. It is observed that the extract of Citrus sinensis acts like a mixed type corrosion inhibitor and its inhibition effectiveness increases on increasing the concentration. The best inhibition effect of the Citrus sinensis extract for low carbon steel in 0.5 M H2SO4 was obtained at 500 mg/L concentration. Further the Langmuir adsorption isotherm was used to check the adsorption behavior of the extract on the metal surface. The surface morphology of the low carbon steel is also studied by using scanning electron microscopy and atomic force microscopy. |
