Molybdenum in steelworks slags – Leaching and sorption
Get product information here:
How much molybdenum is leached out of steelworks slags and what part of it - depending on the substrate's own pH - is subsequently sorbed in underlying soil layers?
Molybdenum in steelworks slags – Leaching and sorption
- Extraction of undisturbed soil columns (D = 30 cm, H = 80 cm) with ecoTech laboratory lysimeters
- Deposition of various steelworks slags with known high molybdenum leaching rates on the soil surface to simulate installation of steel mill slag, e.g. in open road construction
- Irrigation of lysimeters and removal of seepage water with mini-suction cups at different heights of the soil column and at the suction bottom of the laboratory lysimeter
- Analysis of the leachate to investigate the sorption behavior of molybdenum in the soil body
- Accompanying measurements of the redox potential in the soil body and pH in the eluate
