The sorption of H 2 S gas was measured in columns of soils of varying pH, clay, organic‐matter, and Fe‐oxide contents. The amounts and rates of H 2 S adsorption were primarily related to Feoxide content. The soil‐H 2 S sorption was only slightly affected by the H 2 S flow rate. When the H 2 S‐treated soils were exposed to air, the reaction product oxidized to elemental S and Fe oxide within several hours. The oxidation regenerated the H 2 S sorption capacity. The soil were run through four cycles of H 2 S sorption and oxidation without reducing the sorption capacity. The S accumulated in the soil as elemental S.
