More Details: For obtaining environment-friendly and efficient green corrosion inhibitors, the photinia leaf extracts (PTF) were prepared by distilled water reflux method.The corrosion inhibition performance of PTF on Q235 steel in 1 mol/L hydrochloric acid was studied using electrochemical tests, weight loss tests, scanning electron microscopy and other methods.Results showed that as a mixed corrosion inhibitor, PTF could effectively inhibit the corrosion of Q235 steel in hydrochloric acid medium.The corrosion inhibition efficiency increased with the increase of PTF concentration and decreased with the increase of solution temperature.Furthermore, the inhibition efficiency of 4 g/L PTF was 87.99%at 293 K.The results of adsorption isotherm model showed that PTF could spontaneously adsorb on the surface of Q235 steel through physical effects, which conformed to the Langmuir single-layer adsorption model.
