Photoemission of Iodide from Aqueous Aerosol Particle Surfaces

The photoemission of iodide from aqueous aerosol particle surfaces measures the surface concentration of iodide in predominantly supersaturated NaCl aerosol particles. Using the Langmuir model to describe the adsorption to the surface of aqueous iodide anions, the standard Gibbs free energy of adsorption is -15 kJ/mol in these systems. The presence of charged surfactants on the particle surfaces changes the adsorption behavior of iodide. The addition of sodium docecylsulfate (SDS) reduces the coverage of iodide, consistent with a competitive adsorption scenario. For surfaces coated with C-12-, C-14-, or C,(16)-trimethylammonium chloride, the addition of iodide results in the formation of iodide-surfactant ion pairs at the surface with enhanced photoemission. The adsorption free energy for iodide in these systems is -21 kJ/mol. The results demonstrate the surface enhancement of iodide in supersaturated, atmospherically relevant conditions and demonstrate important differences between single-salt solutions and mixtures in the limit of high concentration.

Selective one carbon-carbon bond formation reaction of zirconacyclopentadienes with aryl iodides or alkynyl iodides

Reaction of zirconacyclopentadienes with one equiv or two equiv of aryl iodides in the presence of CuCl and DMPU afforded mono-arylated diene derivatives in high yields with high selectivities. Treatment of zirconacyclopentadienes with one equiv of 2-thienyl iodide similarly gave thienyldienes in the presence of CuCl and DMPU, whereas the reaction with two equiv of 2-thienyl iodide produced thienyl iododiene derivatives in high yields. Zirconacyclopentadienes reacted with two equiv of alkynyl iodides to give iododienynes in good yields in the presence of CuCl. This is in sharp contrast to the reaction with two equiv of alkynyl iodides in the presence of CuCl and DMPU which provides dienediynes. (C) 1997 Elsevier Science Ltd. All rights reserved.

Two new functionalized ionic liquids, 1-acetyl-3-alkylimidazolium iodides, were synthesized by the reactions of 1-acetylimidazole with alkyl iodides under solvent-free condition. Their structures were confirmed by 1 H NMR, ESI-MS, IR, UV-Vis and elemental analysis. The 1-acetyl-3-ethylimidazolium iodide (3a) is a solid and 1-acetyl-3-hexylimidazolium iodide (3b) is a viscous liquid at room temperature.

DETERMINATION OF IODIDE-ION IN IMPREGNATED CHARCOALS BY FLOW-INJECTION

A procedure for the determination of iodide in charcoals impregnated with potassium iodide is described. An aqueous extract is prepared and the iodide ion concentration in this extract (up to 4 x 10(-3) Mol dm-3) is determined by injection into a water stream that is merged with an aqueous solution containing potassium iodate and sulfuric acid, followed by absorptiometric measurement at 460 nm. The analysis is simple and rapid, with a limit of detection of 6 x 10(-5) mol dm-3 iodide and a relative standard deviation (n = 10) of 1.2% for 1 X 10-3 mol dm-3 iodide. The procedure was used to measure the levels and the distribution of potassium iodide in impregnated charcoals. The flow method is discussed with reference to the chemistry of elementary iodine in aqueous solution.

Two consecutive Eley-Rideal reaction steps in a D atom adsorbate interaction: from methylene iodide via methyl iodide to methane

The interaction of gaseous D atoms with methylene iodide molecules adsorbed on graphite monolayer covered Pt(lll) surfaces was studied using direct product rate measurement. At 85 K methane was observed as a reaction product from two consecutive D/adsorbate reaction steps. Via D addition to methylene iodide, adsorbed methyl iodide is formed as an intermediate. Subsequently, D abstracts methyl from methyl iodide towards methane. Approaching and passing the methyl iodide intermediate desorption temperature of 135 K during the reaction, the desorption of the intermediate prevents methane production. The kinetics of methane and intermediate methyl iodide formation is in agreement with the operation of Eley-Rideal reaction steps. This is in accordance with the expectation that on a substrate with a flat adsorption well for atoms from the gas phase the Eley Rideal mechanism should operate in atom/adsorbate reactions.

Determination of iodide in common salts consumed in Turkey by isotope dilution analysis

Iodide traces in common salts consumed in Turkey have been determined by isotope dilution analysis. Iodide was precipitated by stoichiometric amount of AgNO3. Iodide-131 was used as tracer. Electrophoresis was performed to separate (AgI)-I-131 from excess I-131(-). Zone of (AgI)-I-131 was cut Off electrophoresis paper and counted with a NaI(Tl) scintillation counter. Count rates were plotted versus added KI concentrations. Unknown iodide amounts were found by using these linear plots. Iodide concentrations found in analyzed salts were 9-58 mu g/g.

Solvent-Free, Microwave-Assisted Conversion of Tosylates into Iodides

A highly efficient method for the conversion of primary tosylates into the corresponding iodides is outlined. The method involves heating a neat mixture of the tosylate and solid sodium iodide in a microwave cavity. Reaction times are short, usually about 60 minutes, delivering high yields. This procedure is especially useful for the in situ generation of volatile primary iodides, and for most of the primary iodides, the crude product is sufficiently pure.

Vibration spectroscopic evidence for different interactive modes of iodide on gibbsite in humic acid mediation

Determination of the fate of iodide and associated species is an important scientific question from environmental and nuclear energy perspectives. The chemical kinetics of iodide adsorption on gibbsite was examined in the presence of humic acids (HA). The iodide retention was highest in HA-coated gibbsite (I(I) 15.5 mu mol m(2-); pH 6.50) and lowest in HA-iodide-gibbsite ternary systems (I(I) 9.56 mu mol m(2-); pH 6.50). Both inter- and intralayer OH groups have distinguishable IR manifestations for iodide retention on gibbsite. In HA-coated gibbsite, the enhanced iodide retention was ascribed to direct bonding with surface Al-sites.

Kinetics of iodide uptake and efflux in various human thyroid cancer cells by expressing sodium iodide symporter gene via a recombinant adenovirus

We evaluated the potential of radioiodide therapy in human sodium iodide symporter (hNIS)-defective thyroid cancer cells via exogenous hNIS expression. Three human thyroid cancer cells (ARO, FRO and NPA) of different origin were transduced by a recombinant adenovirus encoding hNIS expression cassette (Rad-hNIS). The cells were efficiently transduced by a recombinant adenovirus in a virus dose-dependent manner. Consequently, the hNIS protein could be readily detected by Western blot analysis 48-h post-infection at 10 infectious virus particles per cell. These hNIS-transduced cells actively transported iodide into the cytoplasm at the level of 11635.3, 61571.6, and 19367.5 pmoles/10(6) cells in ARO, FRO, and NPA, respectively. However, a significant amount of iodide was eluted to an iodide-free media within 60 min in all the cell lines. RT-PCR analysis revealed that the expression of genes related to iodide trapping (Tg, TSHR and TPO) was dramatically downregulated in these cells. The present study indicates that functional hNIS can be efficiently expressed and is responsible for active transport of iodide in hNIS-negative human thyroid cancer cells by a recombinant adenovirus. However, the human thyroid cancer cells, along with down-regulation of iodide metabolism-related gene expression, lose the ability to maintain iodide. Therefore, these kinetic characteristics of iodide uptake and efflux may limit the therapeutic potential of hNIS/radioiodide-based treatment following exogenous hNIS expression in human thyroid cancer.
