TL;DR: In this paper, a new high performance liquid chromatography (HPLC) method was developed for the determination of iodine speciation, using anion exchange chromatography and spectrophotometry.

TL;DR: This study applied new analytical techniques to study the sorption and transport behavior of iodine species in sediments collected at the Savannah River and Hanford Sites, and provided quantitative estimates of key parameters (e.g., extent and rate of sorption) for risk assessment at these sites.

TL;DR: Results show that higher concentrations of I(-) (> or =10 microM) had some detrimental effect on plant growth, while IO(3)(-) had little effect on the biomass production of spinach plants.

TL;DR: In this paper, the selectivity coefficients of a quaternary base ammonium anion-exchange resin toward a number of univalent anions have been measured, and two postulated types of specific interactions (ion-pair formation) of these ions with those of the resin matrix were interpreted.
Abstract: Selectivity coefficients of a quaternary base ammonium anion-exchange resin toward a number of univalent anions have been measured. In some systems the selectivity coefficients varied little with composition, while in others a marked dependence was observed. Examples of the former included systems made up of various pairs of ions from Group A-halide, acetate, iodate and nitrate, or of pairs of ions from Group B-thiocyanate, perchlorate, di- and trichlolroacetate, trifluoroacetate, toluenesulfonate and naphthalenesulfonate. Examples of systems where the selectivity coefficient changed markedly were made up of an anion from Group A with one from Group B. These data were interpreted in terms of two postulated types of specific interactions (ion-pair formation) of these ions with those of the resin matrix. The ion-pairs of Group A were assumed to be randomly distributed in the resin phase, while those of Group B were assumed to occur in the form of “patches,” i.e., form clusters. The effect of temperature on the distribution coefficient was small; the concentration of the solution (when dilute) had a negligible effect upon the selectivity.

TL;DR: In this paper, the bridging of the vanadium atoms by the oxo and iodate anions creates zigzagging one-dimensional [VO2(IO3)3O2]1-chains that are separated from one another by...
Abstract: Under mild hydrothermal conditions V2O5 reacts with AIO4 (A = NH4, K, Rb, Cs) and I2O5 to yield A[VO2(IO3)2] (K (1), Rb (2)) and A[(VO)2(IO3)3O2] (A = NH4 (3), Rb (4), Cs (5)) in the form of yellow to dark orange crystals. While 1 and 2 are not isostructural, both contain one-dimensional [VO2(IO3)2]1- chains separated by K+ or Rb+ cations. These chains are constructed from five-coordinate V(V) atoms that are bound by two terminal oxo atoms to create a cis-VO2+ moiety and by one monodentate and two bridging iodate anions to create a distorted square pyramidal geometry. Compounds 3−5 are isostructural and contain orthorhombically distorted, octahedral V(V) with a single terminal oxo ligand. In addition, each vanadium center forms bonds with two bridging oxo atoms that are trans to one another and three bridging iodate anions in a mer arrangement. The bridging of the vanadium atoms by the oxo and iodate anions creates zigzagging one-dimensional [(VO)2(IO3)3O2]1- chains that are separated from one another by ...
