文摘
- •
The inhibition efficiency of the synthesized polyester increases with inhibitor concentration.
- •
The adsorption of the inhibitor obeys Langmuir adsorption isotherm.
- •
Electrochemical impedance spectroscopy experiments have shown that an increase in inhibitor concentration causes an increase in charge transfer resistance Rt and a decrease in Cdl value, owing to the increased thickness of the adsorbed layer.
- •
The Tafel slopes obtained from potentiodynamic polarization curves indicate that all the inhibitors behave as mixed type.
- •
The inhibition efficiency obtained from atomic absorption spectrophotometric studies was found to be in good agreement with that obtained from the conventional weight loss method.
