- Sulfate Removal and Sulfur Transformation in Constructed Wetlands
24 Νοε 2020 · Sulphate (SO42-) concentrations in freshwaters have increased globally over the last decades even though a strong reduction in atmospheric sulphur (S) deposition has occurred across large parts...
20 Δεκ 2001 · Ion-exchange methods are sufficiently sensitive to determine the threshold concentration (Bak et al., 1991), but handling of the sediments may introduce sulphate into depleted layers through reoxidation of sulphide to sulphate or by contamination with overlying water.
In weathering or contact with aerated water, the sulfides are oxidized to yield sulfate ions which are carried off in the water. Sulfate is carried to bodies of water by rain and through solution of sulfate compounds in sedimentary geologic formations within the drainage basin.
21 Φεβ 2023 · The sulphur cycle has a key role on the fate of nutrients through its several interconnected reactions. Although sulphur cycling in aquatic ecosystems has been thoroughly studied since the...
The sulfur cycle can be thought of as beginning with the gas sulfur dioxide (SO 2) or the particles of sulfate (SO 4-2) compounds in the air. These compounds either fall out or are rained out of the atmosphere.
20 Δεκ 2001 · The cycling of sulphur is, however, both spatially and temporally dynamic and strongly influences many biogeochemical reactions in sediments, such as the binding of phosphorus. This review examines the control of sulphate reduction and sulphur cycling in sediments of lakes with different trophic status. 2.
