Two apparent characteristics are observed on the
impedance spectra in Fig.2 on addition of 2M2.Firstly,
the high-frequency capacitive loop increases with increase
in 2M2 concentration.The appreciation of the impedance
can be ascribed to the inhibition of the iron dissolution
process due to the adsorption of 2M2 molecules on the
iron surface.Secondly,the low-frequency capacitive loop/
Warburg impedance increases in length with increase in
2M2 concentration.This is assumed to be due to another
factor that affects the corrosion process.This factor is also
dependent on the 2M2 concentration.
The impedance data were analyzed using the equivalent
circuit (EC) models shown in Fig.3.The circuit comprises
of a hierarchical arrangement consisting of two stacked
resistance-constant phase element pairs.Rs represents the
solution resistance,Q1 and Q2 represent the constant phase
element (CPE),Rct the charge-transfer resistance,and Ra the
equivalent resistance.In the absence of inhibitor (blank),a
negative resistance and capacitance CPE were used to
represent the arcs with an inductive character,since it is
more difficult from a physical view point to justify the use
of very high inductance.This is in accordance with
Macdonald’s approach [34,36].Warburg impedance (W)
was incorporated within the equivalent circuit (Fig.3b) to
model the low frequency response observed in the presence
of the inhibitor.
In order to account for the roughness and inhomogeneities
of the solid electrode [37–39] and the frequency
independent phase shift between an applied AC potential
and its current response [40],the capacitance in the ECs is
substituted by an empirical constant phase element.The
CPE has been extensively described in the literature [41–
43].The impedance,Z,of the CPE is defined as:
where Yo and n are the CPE constant and exponent
respectively,ω is the angular frequency in rad s−1 (ω=
2πf) and j2=−1 an imaginary number.The characteristic
frequencies fmax were obtained from the semicircles
maxima and used to calculate the associated capacitance
(C) from the equation [44]:
The fitting Nyquist plots deduced from the experimental
and simulated data,shown in Fig.4,show that the fitting
results are in good agreements with the experimental data.
In accordance with the EC given in Fig.3b,the
polarization resistance (Rp) is given as:
