Figure 6.8 Hersch galvanic cell for the determination of oxygen at trace levels in gases. Figure 6.8 Hersch galvanic cell for the determination of oxygen at trace levels in gases.
A galvanic cell-type (Hersch cell) coulometer consists of a platinum (Pt) cathode, KBr (or KI) electrolyte (stripping solution), and active carbon anode. When air containing ozone is bubbled into the solution, the bromine (or iodine) liberated by the ozone is reduced at the Pt cathode and hydroxide ion discharges at the carbon anode ... [Pg.3522]
