Rotating silver electrode

Nickel and Liu [79] have studied the silver-catalyzed oxidation of A, A -dimethyl-/7-phenylenediamine by Co(NH3)5Cl3 by means of a silver colloid and a rotating silver electrode. They conclude that the reaction can be quantitatively explained by means of the theory of mixture potential and mixture current of Wagner and Traud...

Dissolution of gold and silver from Au/Ag alloys in aerated cyanide solutions has been investigated using rotating disc electrodes [551]. Dissolution was partially controlled by transport of either oxygen or cyanide. Kinetics of anodic dissolution of gold in cyanide solutions containing different metal ions has been extensively... 

The mechanism of anodic dissolution of silver in cyanide solutions has been studied by Bek and coworkers [378-380]. For example, using [379] the rotating disc electrode and pulse potentiostatic method, it has been found that the limiting step involved the formation, at the electrode surface, of the adsorbed complex with two...

The following data are for the cathodic reduction of thyroxine (one of the iodoamino acid derivatives) at a silver electrode. A disk electrode was rotated at various angular velocities and the current was measured [see R. A. Osteryoung et al., Anal. Chem. 56 1202-1206 (1984)]. 

Kinetics of adsorption were investigated by Pemberton and Buck," who followed the adsorption of dithizone on a rotating-disk silver electrode, on the time scale of a few seconds. Dendramis et reported adsorption of cetyltriammonium on copper in the minute time scale. 

A rotating cylinder electrode (RCE) with a cylindrical or pseudo-cylindrical counterelectrode around it essentially has the geometry of a parallel plate cell. The RCE was developed as a specialty tool for uniform fast electrodeposition in turbulent flow, and for the removal of metal ions from effluents with recovery of the metal in the form of a foil, flake, or powder [61-63]. In the first application, RCE cathodes became the major tool for silver removal from photographic fixer solutions in compact, high-rate units [64], and enabled the recycling of fixer and resale of more than 98 wt% of the silver. Typically, such cells had a stainless steel RCE cathodes of 10-20 cm diameter rotating at speeds up to 1400 rpm, stationary graphite anodes, and were operated at 50 A.

The sodium salt of 5-ethyl-5(l-methylbutyl)-thiobarbituric acid Pentothal, Thiopental) was determinedwith silver nitrate as titrant and either a dropping mercury or rotating platinum electrode. 

In this work we found that halothane interfered with the oxygen currents and we have since shown that halothane can also be reduced quantitatively on a silver cathode [7]. Typical results on the rotating disc electrode are shown in Figure 9. We have shown that the overall reaction is...
