Adsorption / desorption

Soil Adsorption Coefficient i.e Koc value of 2-aminobenzenesulphonic acid was estimated as 10 L/kg (log Koc=1) by means of MCI method. This indicates that 2-aminobenzenesulphonic acid will have a negligible tendency of sorption to soil and sediment and therefore have rapid migration potential to groundwater.This Koc value when converted at 20 degC is equivalent to 8.

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 2-aminobenzenesulphonic acid at 25 deg C is 0.0000000901 Pa m³/mol.
