Corrosion inhibition of carbon steel in hydrochloric acid solution using ethoxylated nonionic surfactants based on schiff base: electrochemical and computational …

Two ethoxylated nonionic surfactants (L400 and L600) based on Schiff base are prepared
from polyoxyethylene, glyoxalic acid, and phenylenediamine. They are evaluated
electrochemically as carbon steel corrosion inhibitors in 1 M HCl by electrochemical
impedance spectroscopy (EIS) and Tafel techniques and complemented with microscopic
analysis methods. The obtained Tafel data indicate the mixed-type behavior of the inhibitor
used. The inhibition efficiency touches the peak at 1× 10–4 M, exhibiting 92 and 94% for …
