Three electrodes were used, a glassy carbon working electrode (Model number = CHI 104, areaofthe electrode = 0.07065 [cm.sup.2]), saturated calomel reference electrode
and a platinum wire auxiliary electrode.
% NaCl) into which the shrouded SPR assembly wasimmersed as working electrode 1 (WE-1), as well as the saturated calomel reference electrode
One Unit It Should Consist Of A Glass Electrode B Calomel Reference Electrode
A typical three-electrode experimental cell equipped with a working electrode, a platinum foil counter electrode, and a saturated calomel reference electrode
(SCE) was used for measuring the electrochemical properties of the working electrode and its performance as a Faradaic electrochemical capacitances (ECs).
The potentiodynamic polarization studies were configured in cells (Figure 1), using three-electrode assembly with a saturated calomel reference electrode
, a platinum counter electrode, and the sample as working electrode in the form of coupons of exposed area of 0.50 [cm.sup.2] or 10 mm x 5 mm.
Photoelectrochemical study was conducted using a Gamry PCI4/750 Potentiostat and a three-electrode system containing CZAS electrode, saturated calomel reference electrode
(SCE), and a platinum counter electrode, which were immersed in an aqueous solution of 0.07 M Eu[(N[O.sub.3]).sub.3] x 6[H.sub.2]O.
All experiments were performed in a three electrode cell containing nickel oxide polyaniline (0.1256 cm2) coated carbon disc electrodes as working electrode, a platinum wire as counter electrode and saturated calomel reference electrode
. All experiments were carried out at room temperature.
Three-compartment cell with a saturated calomel reference electrode
(SCE) and a platinum foil auxiliary electrode was used.
In addition, the use of Ca[Cl.sub.2] or KCl solutions has the advantages of(i) decreasing the effect of the junction potential of the calomel reference electrode
, (ii) equalising the salt content of soils, and (iii) preventing dispersion of the soil (Tan 1995).
