With operations in Kentucky and Oklahoma, Iofina’s strategy is to identify, develop, build, own and operate iodine extraction plants based on the Company’s WET® IOsorb® technology.
2018-6-12 A sample pre-treatment process based on alkaline extraction in the presence of EDTA was optimized for the extraction of these iodine species. Good results were achieved using 10% ammonium hydroxide (v/v) and 0.5 mM EDTA where the transformation between IO 3 − and I − was clearly minimized. The method was applied to several soil reference
Iodine could decrease from 1 g/L to 0.09 g/L after only one-stage extraction. Compared with the extraction of simple iodide, the novel process exhibited a much higher efficiency (91% vs 63%). The molar ratio of I/Cl increased by 600 times compared with the initial aqueous, indicating that the selectivity was high. 2)
Iodine is an essential element for animals and human beings. It ionic iodine (I − and IO 3) and bromine (Br extraction method was used to extract these compounds, which were quantitatively leached with a 10% mass/volume (m/v)
2012-1-15 2.4. Iodine extraction and analysis. After incubation for 114, 306, 810 and 3975 h, samples (∼4.5 g) of moist soil were equilibrated with 20 mL of 0.01 M KNO 3, followed by extraction with 0.15 M KH 2 PO 4 and then 10% TMAH, in 40 mL polycarbonate centrifuge tubes. At each stage soil suspensions were shaken for 16 h on a reciprocal shaker, centrifuged (25 min at 3500 rpm), and filtered
Iodine (I(2)) was detected as an oxidation product that was subsequently further oxidized to iodate (IO(3)(-)). The third order rate constants, second order on iodide and first order on manganese oxide, determined by extraction of iodine in benzene decreased with increasing pH (6.3-7.5) from 1790 to 3.1M(-2) s(-1).
2020-12-7 published extraction procedure4 was used to extract iodine containing species. The extraction solution contained 40 mg pancreatin per 7 mL of 0.2 M KH 2 PO 4 /0.2 M NaOH buffer, pH 8. An aliquot of 0.2 g of sample was accurately weighed into 13 mL round base polypropylene tubes and mixed with 7 mL of extraction solution, then placed into an

2019-5-31 Abstract: The extraction of iodine from seawater is used as a means of analyzing the concentration and isotopic ratios of iodine at different locations in the ocean. This has practical applications in the testing of discharge from nuclear fuel reprocessing plants, tracing of ocean currents, and testing areas for potential environmental and

2020-5-1 Sequential extraction experiments showed that only a small fraction (i.e., 2–15%) of the IO 3 − and I − are adsorbed to the sediment so contributions from reduction/release of adsorbed iodine are small. Moreover, untreated sediment leach experiments showed that by 10 pore volumes (sufficient to desorb iodide

2003-3-29 Iodine is a biologically important trace element. Its behaviour in the environment and in human metabolism is determined by the type of iodine species which takes part in chemical reactions. Knowledge of their concentrations is necessary to understand and describe the iodine reaction paths. A separation procedure is proposed for quick determination of common forms of iodine—iodide, iodate
