Flow injection determination of iodide ion in a photographic developing solution using iodide ion-selective electrode detector

A potentiometric flow injection determination method for iodide ion in a photographic developing solution was proposed by utilizing a flow-through type iodide ion-selective electrode detector. The sensing membrane of the electrode was Ag2S-AgI membrane. The response of the electrode detector as a peak-shape signal was obtained for injected iodide ion in a photographic developing solution. A linear relationship in the subnernstian zone was found to exist between peak height and the concentration of the iodide ion in a photographic developing solution in a concentration range from 0 to 6.0 x 10(-5) mol 1(-1). The relative standard deviation for ten injections of 2 x 10(-5) mol 1(-1) iodide ion in a photographic developing solution was 0.96% and the sampling rate was approximately 12-13 samples h(-1). The iodide ion could be determined under coexisting of an organic reducing reagent and inorganic electrolytes of high concentration in a photographic developing solution sample solution by the present method.

IODIDE BUFFER SYSTEMS FOR THE CALIBRATION OF IODIDE-SELECTIVE ELECTRODES

A new approach to the creation of anion buffer systems is proposed, which extends the linear range. The new iodide buffer systems, containing (1) HgI2 precipitate, CaEDTA(2-), Ca2+, HgEDTA(2-), and (2) HgI2 precipitate, chloride complexes of Hg2+ and excess of Cl- ions, are proposed for the calibration of iodide-selective electrodes at pI > 5. It is shown with the help of these buffers, that a solid-state Orion 94-53 iodide-selective electrode keeps linear Nemstian response up to pI = 7.5. Iodide buffer systems are used for the estimation of the reliability of literature data on selectivity coefficients of iodide-selective electrodes with respect to Cl- ions.

Differential gene expression analysis of iodide-treated rat thyroid follicular cell line PCCl3

The inhibitory effect of supraphysiological iodide concentrations on thyroid hormone synthesis (Wolff – Chaikoff effect) and on thyrocyte proliferation is largely known as iodine autoregulation. However, the molecular mechanisms by which iodide modulates thyroid function remain unclear. In this paper, we analyze the transcriptome profile of the rat follicular cell lineage PCCl3 under untreated and treated conditions with 10 (- 3) M sodium iodide (NaI). Serial analysis of gene expression (SAGE) revealed 84 transcripts differentially expressed in response to iodide (p <= 0.001). We also showed that iodide excess inhibits the expression of essential genes for thyroid differentiation: Tshr, Nis, Tg, and Tpo. Relative expression of 14 of 20 transcripts selected by SAGE was confirmed by real-time PCR. Considering the key role of iodide organification in thyroid physiology, we also observed that both the oxidized form of iodide and iodide per se are responsible for gene expression modulation in response to iodide excess.

Excited state electronic properties of sodium iodide and cesium iodide

We compute from first principles the dielectric function, loss function, lifetime and scattering rate of quasiparticles due to electronic losses, and secondary particle spectrum due to plasmon decay in two scintillating alkali halides, sodium iodide and cesium iodide. Particular emphasis is placed on quasiparticles within several multiples of the bandgap from the band edges. A theory for the decay spectra of plasmons and other electronic excitations in crystals is presented. Applications to Monte Carlo radiation transport codes are discussed.

I-131 HIPPURAN FOR THE ESTIMATION OF RENAL PLASMA-FLOW – REQUIREMENTS FOR RADIOCHEMICAL PURITY

For many years iodide-131 Hippuran has been used as a tracer to measure effective renal plasma flow (ERPF). Because of the low renal clearance of free I-131-iodide and the inability to count it separately from I-131-Hippuran, free I-131-iodide will lower the calculated I-131-Hippuran clearance, resulting in a lower estimated ERPF. This study was performed to establish the maximum allowable radiochemical impurity of free I-131-iodide in I-131-Hippuran preparations for ERPF measurements in continuous clearance studies. A known amount of I-123-iodide was added to the (I-131-iodide-free) I-131-Hippuran solution used for continuous infusion clearance studies in nine patients. I-123-iodide activity was used because it can be counted separately from (131)-I-Hippuran in the infusion solutions and plasma samples while it behaves exactly like I-131-iodide, so that the results obtained with I-123-iodide can be extrapolated to I-131-iodide. After performing the clearance studies, the ERPF was calculated firstly with I-131-Hippuran activity only (=true ERPF) and secondly including the free radioactive iodide activity (=false ERPF) in the clearance formula, As expected, if free I-131-iodide is present in the infusion solution, its concentration in plasma will be highest at the end of the clearance study. The I-131-iodide concentration in plasma relative to the I-131-Hippuran concentration will be higher in patients with high ERPF values. I-131-iodide in the infusion solution causes a fall in the ERPF as measured by the continuous infusion technique: 0.5%, 1% and 2% of free I-131-iodide in the infusion solution result in a reduction in ERPF of about 1.5%, 3.5% and 7% respectively after 1.5 h and of 3.5%, 6.5% and 13% respectively after 5.5 h if ERPF is high. It is concluded that a maximum of 0.5% of free I-131-iodide in I-131-Hippuran preparations is permissible if ERPF is to be measured with an error of less than 5%.

Improved synthesis of phenylethylamine derivatives by Negishi cross-coupling reactions

Trifluoroacetamido-protected beta-aminoalkylzinc iodides undergo Negishi cross-coupling reaction with aryl iodides in moderate to excellent yields (42-84%) based on the corresponding trifluoroacetamido-protected beta-aminoalkyl iodides employing a catalyst prepared in situ from Pd-2(dba)(3) and SPhos (1 2 M ratio) In general meta- and para-substituted aryl iodides give good results using relatively low levels of catalyst [0 25 mol % Pd-2(dba)(3)] but more hindered ortho-substituted examples require higher catalyst loadings The preparation of trifluoroacetamido-protected beta-aminoalkyl iodides is straightforward and the intermediates are significantly more stable than the corresponding Hoc-protected derivatives (C) 2010 Elsevier Ltd All rights reserved

DETERMINATION OF IODIDE BY HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY AFTER PRECOLUMN DERIVATIZATION

Derivatization of iodide into 4-iodo-2,6-dimethylphenol and HPLC of iodophenol with UV detection has been found to be a suitable method for the sensitive detection of iodide. The precolumn derivatization Involved oxidation of iodide with 2-iodosobenzoate at pH 6.4 in the presence of 2,6-dimethylphenol. The reaction mixture was chromatographed on an octadecylsilane column using a mobile phase of acetonitrile-water, 60:40 (v/v), and detection at 220 nm. With an injection volume of 100-mu-L, the detection limit was 0.5 ng of iodide. After complete reaction of iodide at pH 6.4, the solution was adjusted to pH 1 to effect the derivatization of bromide if it was also present with iodide. A mobile phase of acetonitrile-water, 45:55 (v/v), was used for the simultaneous determination of iodide and bromide. The detection limit for bromide was 0.2 ng. Methods have also been evolved for iodine (precolumn reaction without using 2-iodosobenzoate) and iodate (reduction with ascorbic acid to iodide and its derivatization) and for the analysis of iodide, iodine, and iodate in the presence of each other. Application of the method has been made to the determination of iodide in natural water, sea water, iodized salt, milk, and pharmaceuticals. The RSD was in the range 0.4-2.9%.

Kinetic isotope effects in the reduction of methyl iodide

alpha-Deuterium (alpha-D) kinetic isotope effects (KIEs) have been determined for the reaction of methyl iodide with a series of reducing agents. Reagents which transfer hydride ion in an S(N)2 reaction show small inverse or small normal KIEs. Reagents which transfer an electron to methyl iodide to produce methyl radical show large normal KIEs up to 20% per alpha-D. Large KIEs were found for the reaction of methyl iodide with sodium, for Pd-catalyzed reaction of methyl iodide with hydrogen, for electron transfer (ET) at a platinum cathode, for ET from benzophenone ketyl or from sodium naphthalenide, for iron-catalyzed ET from a Grignard reagent to methyl iodide, and for reduction of methyl iodide with tributyltin hydride or with gaseous hydrogen iodide. Very small KIEs were found for electron transfer to methyl iodide from magnesium in ether or from sodium in ammonia. The reason may be that these reactions are transport or diffusion controlled.

An alternative electrolyte based on acetylacetone-pyridine-iodine for dye-sensitized solar cells

We prepared a new organic electrolyte by the reaction among acetylacetone, pyridine and iodine in 3-methoxypropionitrile. The UV-Visible spectra, conductivity measurement and ESI mass spectra were used to study this electrolyte. It was suggested that the quaternization reaction of pyridine took place in this electrolyte solution and two kinds of pyridinium iodide were formed. The efficiency of dye-sensitized solar cells (DSCs) using this electrolyte reaches 6.72%, which is higher than that of DSCs using LiI electrolyte and methylpropylimidazolium iodide electrolyte. It implies that these pyridinium iodides are effective alternative component of iodide for the electrolytes of DSCs. As this organic iodide electrolyte was in situ synthesized based on iodine instead of alkyl iodide, it will be cost-effective and facilitative for the production of DSCs. (C) 2007 Elsevier B.V.
