[Interaction between electrode mercury of polarography and dissolved oxygen in sample solution (author's transl)].

The dissolved oxygen in sample solution produces the reduction wave with remarkable maximum by D.C. polarograph. The height of the maximum wave decreases with the increase of surface and duration of contact with electrode mercury. It has been demonstrated that the decrease of height of maximum wave depends on the decrease of dissolved oxygen in sample solution and the authors have assumed that the decrease of dissolved oxygen is due to the adsorption of oxygen on electrode mercury.
