Studies on the Polarographic Analysis. XII. New Differential Polarography with One Dropping Electrode (2)

Polarographic Oxygen Electrode

A method has been developed for the continuous monitoring of oxygen tension in solutions and gases. The oxygen is reduced at a platinum surface which is covered with a plastic membrane. The silver-silver oxide reference electrode is also included under the membrane. Drift is less than 10 per cent for a period of days, and temperature compcnsation is possible. A number of uses to which it has be...

Automatic polarographic elucidation of electrode mechanisms by means of a knowledge-based system Part 1. Sampled d.c. polarography

A knowledge-based system has been developed for the automatic eluctdatton of electrochemical mechanisms The system IS based on sampled drrect current (or Tast) polarography at a droppmg mercury electrode as a technrque for collectmg experimental mformatton and consists of a general expert system shell for the reasonmg process, the spectftc set of rules and expenmental modules The set of rules a...

A general formulation both for stow elec- Irode reactions at the dropping mercury electrode and for kinetic polarographic cur-

Irode reactions at the dropping mercury electrode and for kinetic polarographic currents was found and the solution derived with the help of dimensionless quantities. The interpolation formula for average kinetic polarographic currents is inagreement with experimentally found dependences on relevant parameters, and it has a form very similar to the older approximate equations of Brdi~kaand Wies...

Reverse Differential Pulse Voltammetry and Polarography

In this paper we obtain the analytical solution for the reverse Werential pulse O P ) technique for a slow electronic transfer process, starting fkom expressions obtained previously for the faradaic response to a triple potential pulse. The solutions are valid for the planar approximations of a static mercury drop electrode and of a dropping mercury electrode. An irreversible reduction process ...
