چکیده
|
The effect of (4z)-2,5-dimethyl-4-(4-methylpyrimido[1,2-a]benzimidazol-2(1h)-ylidene)-2,4-dihydro-3h-pyrazol-3-one (p1) on the corrosion inhibition of mild steel (ms) in 1 m hcl solution was investigated by linear polarization resistance,electrochemical impedance spectroscopy (eis) and weight loss measurements in the presence of different concentrations of p1 ranging from 10-6 m to 10-3 m. the adsorption of p1 on the ms surface was described very well by the langmuir adsorption model and quantum chemical calculations (dft).
