| Popis: | In this study, we test the inhibition behavior of chicken excrement extract for carbon steel in a 1 M hydrochloric acid solution (HCL). The extracts were analyzed by FT-IR. The surface study was performed by analysis of scanning electron microscope (SEM) with energy dispersive X-ray (EDX). Corrosion studies were examined by electrochemical tests. We used impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) at 298 K along with other techniques to measure mass loss at different temperatures (298, 308, 318 and 328 K) with different extract concentrations (0.1; 0.2; 0.4; 0.8 g L−1). The electrochemical and mass loss tests obtained efficiency of 92% and 93% for the concentration of 0.8 g L−1 at 298 K, respectively. By increasing the solution temperature for mass loss, the corrosion resistance of the carbon steel decreased and the yield of the steel increased so that yields of 93, 90, 87 and 82% were obtained at 298, 308, 318 and 328 K, respectively. The results of the potentiodynamic polarization showed that steel corrosion occurs under the control of anodic and cathodic reactions. The isothermal adsorption experiments showed that the adsorptiosn of a chicken excrement extract was spontaneous with physisorption according to Langmuir's isothermal model. |
