Adsorption/Desorption

Soil Adsorption Coefficient i.e Koc value of clioquinol was estimated as 5425 L/kg (Log koc = 3.7343) at 25 deg C by means of MCI method. This indicates that clioquinol will have strong tendency of sorption to soil and sediment and therefore have negligible migration potential to groundwater.

This Koc value when converted at 20 degC is equivalent to 4340.

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 clioquinol was estimated to be 0.00000125 (1.25E-006) Pa m³/mol at 25 degC.
