Mercury Selective Electrode

Interaction of polyadenylic acid with the mercury electrode.

Interactions of polyadenylic acid with the mercury electrode were followed by means of direct current (d.c.), alternating current (a.c.), and pulse polarography. It was ascertained that the electrode reaction of polyadenylic acid did not differ significantly from the reaction of its monomeric components. In contrary to the latter reaction, the polarographic reduction of poly­ adenylic acid take...

An Iridium Based Mercury Film Electrode Part Ii. Comparison of Mercury-film Electrode Behaviors: Theory versus Reality

An experimental study of a 2 mm diameter indium based mercury film rotating disk electrode (IrMFE) is presented. Using anodic stripping voltammetry and test ions of cadmium, lead and zinc, the effects of Hg film thickness on peak potential, half-width and peak height are compared with the predictions given by the De Vries and Van Dalen theory. The response of the Ir-MFE was found to be theoreti...

Mathematical Modelling of the Electrode Process of Azithromycin Using Cyclic Voltammetry at Hanging Mercury Drop Electrode

A theoretical treatment is presented to predict the kinetic behaviour of azithromycin at the surface of hanging mercury drop electrode using cyclic voltammetry. A model is developed to incorporate the occurrence of adsorption of the oxidized and reduced species of azithromycin at the surface of mercury drop electrode. An analytical solution was obtained using MATHEMATICA (V-3, Wolfram Research,...

Spherical Segment Mercury Drops of Variable Size: The BAS Controlled Growth Mercury Electrode

cury electrode (CGME) system uses a large bore capillary (150 μm) with mercury flow regulated via a fast response valve actuated by a computer generated pulse sequence [1,2]. Very short valve opening times offer the possibility of attaining renewable mercury microelectrodes. Such a system offers considerable advantages for in situ measurements in natural waters [3]. There have been few attempts...
