inhibitors for carbon steel in chlorinated environments is very important for
some industrial plants. For this purpose, the inhibitory effect of
5-nitro-2-furaldehyde on the corrosion of carbon steel in aqueous solution of
0.1 M NaCl and 0.1 M HCl was investigated. Cyclic voltagrams were taken to
determine the electrochemical behavior of carbon steel in non-inhibitory and
inhibitory environments. The corrosion rates of carbon steel in the presence of
5-nitro-2-furaldehyde in different concentrations (10, 20, 50 and 100 ppm) were
measured by the Tafel Polarization method. As the inhibitor concentration
increased, no significant change was detected in the 0.1 M HCl medium. In the
0.1 M NaCl environment, the corrosion potential has shifted to values that are
more positive and the corrosion current has been reduced. This indicates that
the inhibitors form a film on the surface of metal in this environment and
create resistance to corrosion. The best inhibitory activity was achieved with
an inhibitor concentration of 100 ppm in 0.1 M NaCl medium. </span> <br /> </p>}, number={2}, publisher={Turkish Chemical Society}
