Test guideline
Qualifier:
no guideline required
Deviations:
no
Principles of method if other than guideline:
The adsorption/desorption coefficient is defined as the ratio between the concentration of the test substance in the soil/sludge and the concentration of the test substance in the aqueous phase at adsorption equilibrium. The adsorption coefficient Koc normalised to the organic carbon of the soil is a useful indicator of the binding capacity of a substance on organic matter of soil or sewage sludge.
