IUPAC-NIST Solubility Data Series. 94. Rare Earth Metal Iodides and Bromides in Water and Aqueous Systems. Part 1. Iodides

This work presents solubility data for rare earth metal iodides in water and in aqueous ternary systems. Compilations of all available experimental data are introduced for each rare earth metal iodide with a corresponding critical evaluation. Every such evaluation contains a tabulated collection of all solubility results in water, a selection of suggested solubility data and a brief discussion of the multicomponent systems. Because the ternary systems were almost never studied more than once, no critical evaluations of such data were possible. Only simple iodides (no complexes) are treated as the input substances in this work. The literature has been covered through the middle of 2011. (C) 2012 American Institute of Physics.

Influence of initial iodide concentration on the iodide uptake by the argillite of Tournemire

Among the radionuclides that can migrate from radioactive wastes buried within consolidated argillaceous rocks, I-129 poses a particular problem due to its high mobility in geomedia and its very long half-life of 1.6 10(7) years. Previous studies carried out on such rocks showed the existence of a low iodide retardation regarding the other anion species. The purpose of the present study was two-fold. It was hoped (1) to confirm this retardation by means of radial diffusion experiments and (2) to estimate the influence of the initial iodide concentrations towards the iodide uptake. The results obtained from in-diffusion stage show that (1) no iodide uptake occurs at high initial concentrations and (2) an uptake at low initial concentrations cannot be clearly evidenced. Finally. the most singular behaviour of iodide was highlighted for all the initial iodide concentrations, from the out-diffusion stage. during which some amount of iodide, available for out-diffusion, were not involved in the diffusion process. Although the origin of such phenomenon remains unclear, a kinetic effect for the iodide uptake was proposed, assuming that the period of 55days (corresponding to the in-diffusion stage duration) would be necessary for inducing the iodide uptake. This kinetic effect, already shown elsewhere by (Descostes. M., Blin, V., Bazer-Bachi, F., Meier, P., Grenut, B., Radwan. J., Schlegel, M.L., Buschaert, S.. Coelho, D, Tevissen, E.

Colorimetric iodide detection in water: a new photo-activated indicator system

The photo-induced conversion of iodide to triiodide is an iodide-specific reaction that has now been optimised to produce a reaction-based indicator system for the iodide anion that functions in water. The observed signal (based on the triiodide anions produced upon photo-irradiation) was further amplified with starch (amylase) to produce a signal that can be detected easily by the naked eye. This approach not only allows for the yes/no discrimination of I- over other anions, it also permits detection of the iodide anion at concentrations of epsilon 30M by simple visual means, as well as in iodised table salt.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 3058-39-7, you can contact me at any time and look forward to more communication. Recommanded Product: 4-Iodobenzonitrile.

Selective Detection of Iodine/Iodide Using BSA-stabilized Gold Nanoclusters-based Fluorescence Probe

In the present study BSA (bovine serum albumin)-stabilized Au nanoclusters (AuNCs@BSA) were demonstrated as a novel fluorescence probe for sensitive and selective detection of iodine/iodide. Beyond that, the proposed method was successfully applied to the determination of iodine in kelp, meanwhile, after iodide was changed to iodine with redox reactions, the detection of iodide could be successfully achieved using the AuNCs@BSA. This method could be used as a reliable, rapid, and cost-effective technique for the determination of iodine/iodide in real samples.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Highly sensitive and selective colorimetric detection of iodide based on anti-aggregation of gold nanoparticles

A simple and reliable colorimetric detection method for iodide has been well established based on the antiaggregation effect of AuNPs in this paper. This assay is highly sensitive and selective toward iodide over other interferent anions due to the high stability of the inorganic complex formed between Hg2+ and iodide. In the absence of iodide, T-rich single-stranded DNA (ssDNA) can specifically bind with Hg2+ to form a stable T-Hg2+-T complex, inducing the solution color change from wine-red to finally violet blue with increasing concentration of Hg2+. However, when Hg2+ is first treated with iodide, the T-Hg2+-T interaction will be interrupted, which results in the anti-aggregation of AuNPs. A linear response from 4 x 10(-8) to 4 x 10(-6) M was obtained for iodide, and a detection limit of 13 nM was achieved.

Effect of iodide on human choriogonadotropin, sodium-iodide symporter expression, and iodide uptake in BeWo choriocarcinoma cells

Context: Active placental transport of maternal iodide by the thyroidal sodium iodide symporter ( NIS) provides an essential substrate for fetal thyroid hormone synthesis. NIS is expressed in trophoblast and is regulated by human choriogonadotropin ( hCG). In thyroid, iodide down- regulates expression of several genes including NIS. Placentas of iodine- deficient rats demonstrate up- regulation of NIS mRNA, suggesting a role for iodide in regulating placental NIS. Objectives and Methods: The objectives were to examine effects of iodide on expression of NIS and hCG in BeWo choriocarcinoma cells. Gene expression was studied by quantitative real- time PCR. Effects on NIS protein expression were assessed by Western blotting. Functional activity of NIS was measured by I-125 uptake. Expression of hCG protein was assessed by immunoassay of secreted hormone. Results: Iodide inhibited NIS mRNA and membrane protein expression as well as I-125 uptake, which were paralleled by decreased beta hCG mRNA expression and protein secretion. Iodide had no effects on pendrin expression. Addition of hCG increased NIS mRNA expression. This effect was partially inhibited by addition of iodide. The inhibitory effects of iodide on NIS mRNA expression were abolished by propylthiouracil and dithiothreitol. Conclusions: We conclude that expression of placental NIS is modulated by maternal iodide. This may occur through modulation of hCG effects on NIS and hCG gene expression.

Acyl iodides in organic synthesis: V. Reactions with carboxylic acid esters

Acyl iodides react with alkyl, alkenyl, and aralkyl esters derived from saturated, unsaturated, and aromatic mono- and dicarboxylic acids in the absence of a catalyst. The reaction involves cleavage of the OR bond and formation of organic iodide RI (including CH2=CHI) and one or two symmetric carboxylic acid anhydrides. Phenyl acetate reacts with benzoyl iodide to give acetyl iodide and phenyl benzoate as a result of cleavage of the (O=)C-O bond. The reaction of diethyl fumarate with acetyl iodide is accompanied by cis-trans isomerization to afford maleic anhydride. In the reactions of acetyl iodide with diethyl oxalate and diethyl malonate, CO and CO2 and CO2 and polyketene are formed, respectively, in addition to ethyl iodide and acetic anhydride. Ethyl esters of strong organic acids, e.g., ethyl trihaloacetates, failed to react with acyl iodides under analogous conditions.
