Investigation of an Isatin Schiff Base as Corrosion Inhibitor in NaCl Solution

Abstract:

Isatin Schiff base, 3-(4-hydroxyphenylimino) indolin-2-one, was investigated as an corrosion inhibitor in NaCl solution. The structure was analysized by X-ray single diffraction. The inhibition and the mechanism of the title compound on the corrosion of high protective Q235A steel in NaCl solution were screened and discussed. The results indicated that it can inhibit the corrosion with moderate inhibition efficiency in different conditions, and the inhibition mechanism of the corrosion inhibiting may be mainly contributed to the adsorption.
