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.

THE INFLUENCE OF LEAD IODIDE AEROSOL DISPERSITY ON ITS ICE-FORMING ACTIVITY

Lead iodide aerosol ice-forming activity obtained by thermocondensation in a cloud chamber has been studied. Lead iodide aerosols have been found to yield a maximum number of 2 x 10(18) kg-1 of ice crystals at 253 K. At 263 K the maximum output amounts to 3 x 10(16) kg-1 and at 268 K lead iodide aerosols are generally inert. Ice-forming characteristics of the lead iodide are inferior to those of silver iodide and copper acetylacetonate, but are better than those of phloroglucinol and copper sulphide. The possibility of producing ice-forming nuclei with 10-fold reduced lead iodide content is considered by coating inert nuclei with small quantities of active substance. The activity of such coated nuclei is estimated.

The determination of iodide based on a flow-injection coupling irreversible biamperometry

A novel flow-injection irreversible biamperometric method is described for the direct determination of iodide. The method is based on electrochemical oxidation of iodide at the gold electrode and the reduction of permanganate at the platinum electrode to form an irreversible biamperometric detection system. Under the applied potential difference of 0 V, in the 0.05 mol/L sulfuric acid, iodide can be determined over the range 4.00×10(-7)-1.00×10(-5) mol/L with a sampling frequency of 120 samples per hour. The detection limit for I is 3.0×10(-7) mol/L and the RSD for 40 replicate determinations of 4.0×10(-5) mol/L potassium iodide is 1.68%. The new method was applied to the analysis of iodide in table salt with satisfactory results.

Effect of annealing on the laser induced photoluminescence behavior of template-synthesized silver iodide nanowires

Silver iodide nanowires have been fabricated using non-galvanic template synthesis technique. The effect of annealing on the laser induced photo luminescent behavior of silver iodide nanowires has been studied. It is established that due to annealing, emission wavelength of silver iodide nanowires change. In comparison with un-annealed nanowires, the emission wavelength is found to decrease with the increase in annealing temperature and annealing time as well. These studies are very important as silver iodide is a very useful candidate for photography applications.

A simple and efficient phosphorescent probe for iodide-specific detection based on crystallization-induced phosphorescence of organic ionic crystals

It is very challenging to develop luminescent detection methods for iodide ions due to their significant fluorescence quenching of general fluorophores induced by the heavy-atom effect. Herein, we reveal a unique crystallization-induced bright phosphorescence of tetraphenylphosphonium iodide (TPP I) and develop a novel time-gated detection method for iodide ions to minimize the autofluorescence from complex biological samples. Both the involvement of heavy iodide ion and accessible ionic interaction-induced organic crystals contribute to the accomplishment of a very high phosphorescence quantum yield (0.42) for TPP I. This specific iodide-triggered bright organic phosphorescence enables the development of a novel time-gated detection method for iodide ions in the luminescence turn-on manner and further offers an opportunity to establish a facile test strip for the visual detection of iodide ions based on solid-state phosphorescence on a solid substrate. Excellent performance of this probe in imaging iodide in live cells and intriguing use in double encryption illustrate the versatile and broad application prospects of highly efficient organic ionic crystals in various areas.

SEPARATION OF IODIDE AND IODATE BY ANION-EXCHANGE RESIN AND DETERMINATION OF THEIR IONS IN SURFACE-WATER

Analytical methods for the determination of iodide and iodate ions in surface water were investigated. Iodide in water was adsorbed on an anion exchange resin column and eluted as iodate which was then oxidized with permanganate. For the colorimetric determination of iodide, the Leuco Crystal Violet method was adopted. To obtain the concentration of iodate in surface water, total iodine was determined by a similar analytical method after reducing iodate to iodide with sulfurous acid. The concentration of iodate was calculated by subtracting the concentration of iodide from that of total iodine. The concentration of total iodine was 2.5-mu-g/l in rain water and 5 approximately 7-mu-g/l in river and tap waters. The analytical results of iodide and iodate in rain and river waters showed that the ratio of iodate to iodide in river water was higher than that in rain water. On the other hand, the analytical results for tap water showed that its ratio of iodate to iodide was conspicuously higher than that of river water.

Crystalline nanostructures of heavy metal iodides

Heavy metal iodides such as mercuric iodide and bismuth tri-iodide are among the materials with the best properties for room temperature semiconductor detection. The use of nanostructures of these compounds – recently synthesized – as precursors for nucleation of oriented layers, opens new perspectives for layer growth and, through them, the possibility of a new generation of detectors with enhanced imaging performance. The mentioned heavy metal iodides were synthesized in this work in 1-octadecene as solvent, using octadecanethiol (ODT) or trioctylphosphine (TOP) as capping agents. This is the first report of morphology and size control of mercuric iodide and bismuth tri-iodide nanostructures using capping agents. We obtained promising results for mercuric iodide with ODT and for bismuth tri-iodide with TOP, which will start a new trend in nucleation of heavy metal iodides. (C) 2014 Elsevier B.V.

PROPRANOLOL HAS DIRECT ANTITHYROID ACTIVITY – INHIBITION OF IODIDE TRANSPORT IN CULTURED THYROID-FOLLICLES

The effect of propranolol on the process of thyroid hormone formation was studied in a physiological culture system. Porcine thyroid follicles were preincubated with propranolol for 24 h. Iodide transport, iodine organification, and de novo thyroid hormone formation were measured by incubating these follicles with the mixture of carrier-free 0.1 muCi (NaI)-I-125 and 50 nm NaI for 2 to 6 h at 37-degrees-C. A concentration of propranolol greater than 100 mum inhibited iodide transport in a dose-dependent manner; this inhibition was non-competitive with iodide and independent of thyrotropin (TSH). Reduced iodine organification and thyroid hormone formation was seen with 150 mum propranolol or greater. The inhibitory action of propranolol was not caused by beta-blocking activity, since D-propranolol (devoid of beta-blocking activity) inhibited iodide transport, and other beta-blockers (metoprolol, atenolol, and labetalol) did not inhibit iodide transport. The inhibition of iodide transport was most likely caused by membrane stabilizing activity since quinidine, which possesses the same membrane stabilizing activity as propranolol, also inhibited iodide transport. TSH-mediated cAMP generation and Na+K+ATPase activity, membrane functions for iodide transport, were unaffected by propranolol. Our study has shown, for the first time, that propranolol has a direct antithyroid action, namely inhibition of iodide transport in the intact thyroid follicle.
