Description of key information

The 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) at 25 deg C , by the MCI method. Thus suggesting that 4-aminobenzene-1,3-disulphonic acid shows low sorption to soil and sediment, and moderate migration potential to groundwater. This koc value is equivalent to 27.032  (log koc as 1.43) at 20 deg C.

Additional information

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.
