Transport and Distribution :

Adsorption and desorption :

Soil Adsorption Coefficient i.e Koc value of phthalylsulfathiazole was estimated as 685.1 (log Koc : 2.8357) at 25 deg C by means of MCI method. This indicates that phthalylsulfathiazole will moderately adsorb to the organic carbon fraction of the soil and will have a slow migration potential to groundwater. The key value of Koc at 20 deg C is equivalent to 548.08 (log Koc :2.7388 )

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.

Henry's Law Constant of phthalylsulfathiazole was estimated to be 0.0000000000000000766017 Pa m³/mol at 25 deg C.
