Adsorption / desorption

The Soil Adsorption Coefficient i.e Koc value of Eicosanoic acid was estimated as 38850 L/kg by means of MCI method. This indicates that Eicosanoic acid will have a very strong tendency of sorption to soil and sediment and therefore havenegligiblemigration potential to groundwater.This Koc value when converted at 20 degC is equivalent to 31080.

Henry's Law constant

Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.Henrys Law Constant of Eicosanoic acid at 25 deg C is 9.1 Pa m³/mol.
