Nyquist plots show a semicircle in each curve that stands for a time constant because of the charge transfer resistance. Increasing concentration leads to enlarging the capacitive loop diameter, which means the inhibition effect is getting improved. Formula (9) was applied to study the inhibition ...
Reflux of isatin with thiosemicarbazide in ethanol with the addition of a few drops of acetic acid was conducted in order to synthesize the target corrosion inhibitor. The corrosion inhibitor has a molecular weight of 188, which was determined using the chemical formula (C9H8N4O) and confirmed ...
