Chemical equilibria of sulfides in submerged soils as studied with a hydrogen sulfide sensor

, : Chemical equilibria of sulfides in submerged soils as studied with a hydrogen sulfide sensor. Soil Science 134(3): 171-175

An electrochemical H2S sensor was constructed for use in the measurement of H2S in soils. The pH2S changed nearly linearly with the change of pH, with a slope of 0.8 to 1.1 for the 3 soils studied. The slope for the dependence of pS2- on pH was 1.1 to 1.5. The addition of ferrous Fe to the soil resulted in the decrease in the concentration of soluble H2 S. There was a peak in H2 S concentration after 3-4 days' submergence. Later, the H2S concentration may maintain a rather high level, even in the presence of a large amount of water-soluble ferrous Fe. The (pFe2+ + pS2-) value was not a constant, but decreased with the increase in pH.
