the applicability of a new organic inhibitor extracted from a cheap organic waste of orange peel
(so-called „green” inhibitor) was studied in a laboratory system where the steel rebar samples
obtained from a steel mill operating in Hungary were investigated in several sets of experiments
to reveal their major corrosion properties in aqueous solutions containing sodium chloride salt.
the initial corrosion rates were determined by a standard electrochemical polarisation technique
on active (scale and rust free) steel specimen while being immersed in 3.5% nacl aqueous
solutions containing the methanol extract of the chosen green inhibitor in a preliminary test run
of 24 hours. Due to the inhibitor’s active groups identified by Ftir spectroscopy, this new green
inhibitor (with concentrations tested at 1 and 3%) showed promising surface adsorptive and
corrosion mitigating effects examined also by scanning electron microscopy (sem) combined
with eDs surface analysis. these sem-eDs surface analyses were performed on the given rebar
samples after an immersion (i.e. corroding) period of one month.
