  • Iodine fractionation in agricultural and forest soils ...

    For total iodine extraction from soils less than 0.5 mm, particle-sized soil was used. Total iodine content in the selected soil samples was determined by single extraction method with tetramethylammonium hydroxide (TMAH) modified according to Yamada et al. (1996) and Fecher et al. (1998). 100 mg of finely ground soil and 5 ml 5% TMAH (Alfa Aesar, Karlsruhe, Germany) were added to 15 ml ...

    May 01, 2015  At 1 d after iodine addition, more than 70 % of the iodine added as I − was extracted from the soil samples, whereas the extraction yield was lower for iodine added as IO 3 − to each of the soil samples (Figure 4). The higher soil solubility of I − relative to that of IO 3 − agrees with previously reported results (2, 13–15).
