The Action of Hydrogen Sulfide on Polarographic Oxygen Sensors

  • J. M. Hale


It is often necessary to measure oxygen concentrations in water containing dissolved hydrogen sulfide (Chap. III.l). Conventional polarographic oxygen sensors (POS) fail within a very short time under such conditions, for a variety of reasons to be described in this article. The principle of the modified sensor made by Orbisphere which may be exposed to high concentrations of H2 S is also described.
