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 (SCE).
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).
