Cyclodextrin-accelerated oxidation of iodide by oxygen in aqueous solutions containing HClO4

The oxidation of iodide to I-3(-) by oxygen dissolved in water containing HClO4 has been found to be accelerated by alpha-cyclodextrin (alpha-CD). Among alpha-, beta-, and gamma-CDs, alpha-CD is the most effective mediator for the oxidation reaction of iodide by oxygen. The oxidation rate of iodide is first order in the concentrations of alpha-CD and HClO4, whereas it is second order in the KI concentration.

Simultaneous determination of bromide and iodide ions by capillary isotachophoresis using quaternary ammonium salts

Bromide and iodide ions were determined simultaneously by capillary isotachophoresis using an aqueous electrolyte system; the separation principle was based on the ion-pairing equilibria between tetradecyldimethylbenzylammonium ion and these anions in the leading electrolyte. The interaction between iodide ion and tetradecyldimethylbenzylammonium ion was stronger than that for bromide ion. Thus complete separation of bromide and iodide ions could be obtained by using a leading electrolyte containing 1.5 mM tetradecyldimethylbenzylammonium ion. The pH of the leading electrolyte was adjusted to 5.0. The relative standard deviations of the zone length for bromide and iodide ions were 1.1 and 1.2%, respectively, when mixture of 3.0 mM of these ions was analysed. A 150-mu l volume could be injected for the simultaneous determination of low concentrations of bromide and iodide ions.

Recent Advances in Luminescent Recognition and Chemosensing of Iodide in Water

This Minireview covers the latest developments of chemosensors based on transition-metal receptors and organic fluorophores with specific binding sites for the luminescent detection and recognition of iodide in aqueous media and real samples. In all selected examples within the last decade (made-post 2010), the iodide sensing and recognition is probed by monitoring real-time changes of the fluorescence or phosphorescence properties of the chemosensors. This review highlights effective strategies to iodide sensing from a structural approach where the iodide recognition/sensing process, through supramolecular interactions as coordination bonds, hydrogen bonds, halogen bonds and electrostatic interactions, is transduced into an optical change easily measurable. The selective iodide sensing is an active field of research with global interest due to the importance of iodide in biological, medicinal, industrial, environmental and chemical processes.

A biologically based dose-response model for dietary iodide and the hypothalamic-pituitary-thyroid axis in the adult rat: Evaluation of iodide deficiency

A biologically based dose-response (BBDR) model was developed for dietary iodide and the hypothalamic-pituitary-thyroid (HPT) axis in adult rats. This BBDR-HPT axis model includes submodels for dietary iodide, thyroid-stimulating hormone (TSH), and the thyroid hormones, T(4) and T(3). The submodels are linked together via key biological processes, including (1) the influence of T(4) on TSH production ( the HPT axis negative feedback loop), (2) stimulation of thyroidal T(4) and T(3) production by TSH, (3) TSH upregulation of the thyroid sodium (Na(+))/iodide symporter, and (4) recycling of iodide from metabolism of thyroid hormones. The BBDR-HPT axis model was calibrated to predict steady-state concentrations of iodide, T4, T3, and TSH for the euthyroid rat whose dietary intake of iodide was 20 mu g/day. Then the BBDR-HPT axis model was used to predict perturbations in the HPT axis caused by insufficient dietary iodide intake, and simulation results were compared to experimental findings. The BBDR-HPT axis model was successful in simulating perturbations in serum T4, TSH, and thyroid iodide stores for low-iodide diets of 0.33-1.14 mu g/day. Model predictions of serum T(3) concentrations were inconsistent with observations in some cases. BBDR-HPT axis model simulations show a steep dose-response relationship between dietary intake of iodide and serum T(4) and TSH when dietary iodide intake becomes insufficient (less than 2 mu g/day) to sustain the HPT axis. This BBDR-HPT axis model can be linked with physiologically based pharmacokinetic models for thyroid-active chemicals to evaluate and predict dose-dependent HPT axis alterations based on hypothesized modes of action. To support continued development of this model, future studies should include time course data after perturbation of the HPT axis to capture changes in endogenous iodide, serum TSH, T(4), and T(3).

Double Salts Iodide Scintillators: Cesium Barium Iodide, Cesium Calcium Iodide, and Barium Bromine Iodide

In this study we review the state-of-the-art for double salt iodide scintillators, in particular cesium barium iodide (CBI), cesium calcium iodide (CCI) and barium bromine iodide (BBI), as well as report on their scintillation and optical properties. Double salt iodides inherently have high density and atomic number which translates to good stopping power for energetic particles, in particular gamma rays. Light yields of 54,000 ph/MeV for CBI, 51,000 ph/MeV for CCI, and 46,000 ph/MeV for BBI were measured. A FWHM energy resolution for the 662 keV full absorption peak was observed at 5.7% for CBI, 16.3% for CCI and 3.56% for BBI. The principal scintillation decay timing for CBI was 840 ns, 462 ns for BBI, and two distinct time components of 9 ns and 1900 ns were observed for CCI.

FLOW-INJECTION PROCEDURES FOR DETERMINATION OF IODIDE AND IODATE IODIDE WITH SPECTROFLUORIMETRIC AND SPECTROPHOTOMETRIC DETECTION, RESPECTIVELY

Iodide was determined using a flow-injection system based on the catalytic reduction of cerium(IV) to fluorescent cerium(III) [lambda(ex) = 260 nm, lambda(em) = 350 nm]. Iodate and iodide were determined spectrophotometrically by a sensitive colour reaction with p-aminophenol. Iodide was oxidized by hydrogen peroxide to iodate in the presence of p-aminophenol. Iodate in turn oxidized p-aminophenol to an indamine dye which has an absorbance maximum at 540 nm.

A flow injection method is described for the sequential determination of chloride and iodide in a mixture of the two. The chloride-iodide mixture is precipitated from solution by silver nitrate and the precipitated silver chloride is dissolved by ammonia solution to determine chloride after which the precipitated silver iodide is dissolved by potassium cyanide solution to determine iodide. The method allows the analysis of about 15 samples h-1 and mixtures with different chloride: iodide ratios can be analysed at the mu-mol dm-3 level.
