Description of key information
Additional information
No studies on the transport and distribution of iodine pentafluoride are available or can be performed as in contact with water iodine pentafluoride reacts instantly and violently under formation of hydrogen fluoride and iodate. Hydrogen fluoride will further react to fluoride and iodate in water forms an equilibrium with iodide. Therefore available data from studies with fluoride, iodate and iodide are given as indication of the sorption properties of iodine pentafluoride.
A series of experiments with iodate and iodide were performed in a variety of soils with distinct properties as to pH, cation exchange capacity, soil organic matter content and ferric/aluminum oxides content. It was found that iodate and iodide adsorption isotherms could be well fitted with both the Langmuir and the Freundlich equations. From the available data sorption distribution coefficients (Kd) were determined. Kd values ranged from 0.2 to 1.97 L/kg for iodide and from 0.85 to 53.75 L/kg for iodate. Although the organic carbon contents are not reported they were calculated from soil organic matter contents. For iodide the Koc values range from 20 to 187 L/kg with a geometric mean Koc value of 74 L/kg for all soils combined. For iodate the Koc values range from 35 to 10237 L/kg with a geometric mean Koc value of 377 L/kg.
For the sorption characteristics of fluoride only qualitative data are available. Altogether, the immobile character of fluoride in soil is likely to be due mainly to formation of complexes with aluminium, iron or calcium and dependent on the pH and the availability of these counter ions. Although some true adsorption processes are described (e.g. displacement of hydroxide from clay surfaces) these processes are probably of lesser significance. For pragmatic reasons, for environmental exposure assessment a Koc is calculated based on a log Kow of -1 in EUSES (in the EU-RAR for hydrogen fluoride a log Kow of -1.4 is suggested). When using the QSAR for non-hydrophobics (default QSAR), a Koc of 3.16 is determined.
