Adsorption / desorption

The adsorption potential of Fe(Na)HBED was investigated in an experiment with different focuses on chelating agents and on the basis of OECD Guideline 106 / EU Method C.18 (Lucena, López-Rayo and Hernández, 2009).

The following conclusions are reported: The test substance possesses low soil reactivity since only some interaction with peat has been observed. Displacement by other cations seems to be of low importance. Furthermore, it is able to maintain a significant amount of Fe in solution when interacting with soil for a longer time.

The EPIWIN software KOCWIN v2.00 was used to predict the soil adsorption coefficient via the MCI as well as the traditional method. The values are reported as 67.13 L/kg and 0.02828 L/kg, respectively. Due to improved correction factors, the MCI method is taken more seriously into account and is therefore considered as the key value for the chemical safety assessment.
