All measurements show well-defined peaks around 1.02 V (vs saturated calomel electrode
) as indicated by the long arrows in panels A, C, and E of Fig.
Similarly, the sample was set as a working electrode with an exposed area of 1 [cm.sup.2], a piece of platinum sheet as a counter electrode, and the saturated calomel electrode
as a reference electrode.
For understanding the corrosion response of steel reinforcement in concrete, half cell potential measurements were carried out using saturated calomel electrode
(SCE) and high impedance voltmeter (HP E2378A).
An open circuit potential (OCP) measurement was conducted by using a saturated calomel electrode
(SCE) as the reference electrode and carbon steel as the working electrode in a standard electrochemical glass cell with the SRB medium as electrolyte.
Saturated calomel electrode
(SCE) of KP-113 type served as reference electrode, whereas platinum electrode PtP-201 was used as auxiliary electrode.
Photocurrent densities were measured in a standard three-electrode configuration with the TNT arrays as a photo-anode electrode, Pt-ITO foil as the counter electrode, and a saturated calomel electrode
(SCE) as the reference electrode.
Cyclic voltammogram (CV) of the sample was carried out in a three-electrode cell (PANI as a working electrode, Pt-foiled as a counter electrode, and saturated calomel electrode
(SCE) as a reference electrode) using a CHI660A electrochemical workstation (CH Instrument, CN).
A platinum electrode and saturated calomel electrode
(SCE) were used as counter and reference electrode, respectively.
Under chronoamperometric experiments carried out at a constant applied potential of 0.95 V vs saturated calomel electrode
, the linear range (r 2greater than0.995) was determined to be at least three decades and the limit of detection range from 26 mM (ethylamine) and 65 mM (tert-butylamine), for the investigated amino compounds.
A saturated calomel electrode
(SCE) and platinum wire (3 mm diameter) were used as reference and auxiliary electrodes respectively.
The electrolytic cell was a standard three-electrode system containing platinum electrode (area 2.25 cm2) was a auxiliary electrode, a saturated calomel electrode
was a reference electrode, a smoothly polished stainless steel (10 mmx10 mmx1 mm) was a working electrode in the test, the concentration is 0.02 mol/L and the scan rate is 2 mV/s.
The reference electrode was saturated calomel electrode
(in this paper, if there were no special instructions, the potential was defined relatively to the saturated calomel reference electrode).
