Description of key information
Additional information
Adsorption / desorption
Soil Adsorption Coefficient i.e Koc value of 4-aminobenzene-1,3-disulphonic acid was estimated as 33.79 L/kg (log koc as 1.528)by means of MCI method. This indicates that 4-aminobenzene-1,3-disulphonic acid will have low tendency of sorption to soil and sediment and therefore have moderate migration potential to groundwater.
This koc value is equivalent to 27.032 (log koc as 1.43) at 20 deg C.
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 4-aminobenzene-1,3-disulphonic acid which is a liquid at 25 deg C was estimated as 4.21E-014 Pa-m3/mole
