SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF IODIDE BY ITS CATALYTIC EFFECT ON THE CHLORPROMAZINE-HYDROGEN PEROXIDE REACTION

A catalytic photometric method for the determination of trace amounts of iodide is proposed. In the presence of iodide, chlorpromazine is oxidized by hydrogen peroxide in a sulfuric acid solution to form a red intermediate, which is further oxidized to a colorless compound. The reaction is followed by measuring the increase in the absorbance at 525 nm; the maximum absorbance is obtained on an absorbance-time curve at a given reaction time. Since the maximum value increases with an increase in the iodide concentration, this value is used as a parameter for the iodide determination. Under the optimum experimental conditions (1.0X10(-3) M chlorpromazine, 1.5 M sulfuric acid, 2.0 M hydrogen peroxide, 30-degrees-C), iodide in the range 0.2-10-mu-g l-1 can be determined. The relative standard deviations are 0.8, 2.6 and 4.2% for 6.0, 2.0 and 0.6-mu-g l-1 iodide, respectively. Although iodate shows the same catalytic effect as iodide at the same concentration as iodine, free iodine shows a somewhat lower catalytic effect. The procedure has been applied to the determination of iodide in natural water samples.

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.

Long-range correlations in iodide cluster aggregates

The morphology of tin iodide deposits grown during gas-solid transformation demonstrated long-range correlations. These iodide deposits include basically two kinds of forms: fractal structure and dendritic-like structure. The fractal structure was a sort of tin iodide cluster aggregation. Each fractal structure was composed of numerous tin iodide clusters that connected or disconnected with each other. The average size of fractal structures is between 10 and 22 mu m. The dendritic-like structure was also composed of many tin iodide clusters. These clusters aggregated and formed a dendritic pattern.

Biocompatible Choline Iodide Catalysts for Green Living Radical Polymerization of Functional Polymers

Herein, nontoxic and metabolizable choline iodide analogues, including choline iodide, acetylcholine iodide, and butyrylcholine iodide, were successfully utilized as novel catalysts for green living radical polymerization (LRP). Through the combination of several green solvents (ethyl lactate, ethanol, and water), this green LRP process yielded low-polydispersity hydrophobic, hydrophilic, zwitterionic, and water-soluble bio-compatible polymethacrylates and polyacrylates with high monomer conversions. Well-defined hydrophobic-hydrophilic and hydrophilic-hydrophilic block copolymers were also synthesized. The accessibility to a range of polymer designs is an attractive feature of this polymerization. The use of nontoxic choline iodide catalysts as well as green polymerization conditions can contribute to sustainable polymer chemistry.

Capture and Recovery of Organic Iodide Species from the Product Stream of a Process for the lodative Dehydrogenation of Ethane to Ethylene

A method has been proposed for the capture and recovery of organic iodides produced in the iodative dehydrogenation of ethane to ethylene. Bench-scale experiments have identified ethyl iodide as well as vinyl iodide as the main organic iodide species at levels of several hundred ppmv in the products. The capture, recovery, and recycle of these organic iodides in an absorber-stripper system, using a heavy hydrocarbon absorbing medium, has been modeled and shown to be effective in removing these organic iodide species from the hydrocarbon product stream, reducing concentrations down to around 50 ppbv levels, which enables iodine losses from the process to be maintained at economically acceptable levels.

Protection by iodide of lens from selenite-induced cataract

Background. Iodide has been used empirically against different age-related eye diseases, including cataract. The purpose of the present study was to investigate the effect of iodide on selenite-induced cataract in rat lens. Methods. Young white rats received subcutaneously sodium selenite (20 and 30 nmol/g b.w.) on day 13 post partum (p.p.). Cataract development was measured by expert estimation and image data analysis. Potassium iodide (1.5 nmol/g b.w.) was given (1-5 times) i.p. at different times with respect to the selenite administration. Lens opacification was analyzed in selenite, selenite-iodide, iodide and control groups on day 7 after selenite administration. Results. Iodide showed a significant protective effect against selenite cataract when injected 2 days (2 times) before selenite injection, i.e., on days 11 and 12 p.p. No significant effects on lens opacity were found: (1) after only one iodide injection (on day 12 p.p.), (2) after an initial iodide administration 1 h before selenite and (3) after injections of iodide once a day for 5 consecutive days. The protective effect of iodide was the same (about 50%) for both selenite doses used. Conclusions. There is a time-dependent protective influence of iodide against selenite cataract development. It is supposed that the anticataract effect of iodide could be based on direct or indirect antioxidant mechanisms.

Study of the mechanism of the electrochemical deposition of silver from an aqueous silver iodide suspension

The present work examines the reduction of solid silver iodide on a silver electrode and proposes a mechanism for this process. Voltammetric and coulometric studies for the steady and transient states showed adsorption of silver iodide at the electrode depending on its concentration; this adsorption is in accordance with the Langmuir isotherm for low concentrations and with multi-layer models (such as the BET isotherm) for higher concentrations. Reduction of silver iodide at the silver electrode can take place through several processes such as direct reduction of solid particles, or reduction of the adsorbed silver iodide and involves the formation of a dendritic silver deposit not adhering to the electrode and free iodide in solution. Silver is then recovered easily by filtration of the initial suspension. (C) 2000 Elsevier Science B.V. All rights reserved.

Electrosynthesis of polypyrrole in iodide solution. Film growth, redox behaviour and potentiometric response

Electrosynthesis of polypyrrole (PPy) was studied in aqueous lithium iodide solution. The electrochemical polymerization showed features of two-dimensional growth and the reaction was catalyzed by the I-2/I- couple. The potentiometric response of PPy doped with iodide (PPy(I)) was studied both in iodide solutions and solutions containing the redox couple I-2/I- with a fixed concentration ratio 0.4 but varying the initial concentration of iodide in the range 10(-5)-1.0 M. Linear, anionic response was observed in the concentration range 10(-1)-10(-3) M when only iodide species was present. However, contribution of the redox response to the overall potentiometric response increased with increasing concentration of I-2 although the concentration ration between iodine/iodide was kept constant. The influence of phosphate buffer on the electroactivity of PPy doped with iodide was also studied. (C) 1997 Elsevier Science B.V.

Production of Molecular Iodine and Tri-iodide in the Frozen Solution of Iodide: Implication for Polar Atmosphere

The chemistry of reactive halogens in the polar atmosphere plays important roles in ozone and mercury depletion events, oxidizing capacity, and dimethylsulfide oxidation to form cloud-condensation nuclei. Among halogen species, the sources and emission mechanisms of inorganic iodine compounds in the polar boundary layer remain unknown. Here, we demonstrate that the production of tri-iodide (I-3(-)) via iodide oxidation, which is negligible in aqueous solution, is significantly accelerated in frozen solution, both in the presence and the absence of solar irradiation. Field experiments carried out in the Antarctic region (King George Island, 62 degrees 13’S, 58 degrees 47’W) also showed that the generation of tri-iodide via solar photo-oxidation was enhanced when iodide was added to various ice media. The emission of gaseous I-2 from the irradiated frozen solution of iodide to the gas phase was detected by using cavity ring-down spectroscopy, which was observed both in the frozen state at 253 K and after thawing the ice at 298 K. The accelerated (photo-)oxidation of iodide and the subsequent formation of tri-iodide and I-2 in ice appear to be related with the freeze concentration of iodide and dissolved O-2 trapped in the ice crystal grain boundaries. We propose that an accelerated abiotic transformation of iodide to provides a previously unrecognized formation pathway of active iodine species in the polar atmosphere.
