Carbon dots-based fluorescent probes for sensitive and selective detection of iodide

We report on a simple method for the determination of iodide in aqueous solution by exploiting the fluorescence enhancement that is observed if the complex formed between carbon dots and mercury ion is exposed to iodide. Fluorescent carbon dots (C-dots) were treated with Hg(II) ion which causes quenching of the emission of the C-dots. On addition of iodide, the Hg(II) ions are removed from the complex due to the strong interaction between Hg(II) and iodide. This causes the fluorescence to be restored and enables iodide to be determined in the 0.5 to 20 mu M concentration range and with a detection limit of similar to 430 nM. The test is highly selective for iodide (over common other anions) and was used for the determination of iodide in urine.

A 96-well automated radioiodide uptake assay for sodium/iodide symporter inhibitors

A high-throughput screening method based on radioiodide uptake in human embryonic kidney 293 cells expressing the human sodium/iodide symporter was developed. Central to assay development was a homogeneous cell culture in the 96-well microplate coupled with the use of scintillation proximity technology. The assay is fast and highly reproducible with a Z ‘ greater than 0.8. The automated procedure allows the screening of 4,000 compounds per day. Using this methodology, several known substrates of the sodium/iodide symporter were evaluated in a single day. Inhibition of iodide uptake was shown to follow the series PF6- > ClO4- > BF4- > SCN- >> NO3- > IO4- > N-3(-) >> Br-, in accord with the literature. This method represents an initial approach to the search for inhibitors of iodide transport mediated by the sodium/iodide symporter.

Di(ethylxanthate) complex of cobalt(II) as neutral carrier for highly selective iodide electrode

A new solvent polymeric membrane electrode based on di(ethylxanthate) complex of Co(II) is described which demonstrates excellent selectivity toward the iodide ion.The resulting electrode exhibits fairly low detection limits and good selectivity properties.The selectivity sequence observed is iodide > thiocyanate > nitrite > bromide>perchlorate>sulfate>nitrate>chloride. The excellent selectivity for iodide is related to the unique interaction between the central Co(II) ion and iodide. The response mechanism of the electrode was also studied with the ac impedance and spectroscopic techniques.

Perfluorooctane sulfonic acid, a persistent organic pollutant, inhibits iodide accumulation by thyroid follicular cells in vitro

Poly- and perfluoroalkyl substances (PFAS) are a class of endocrine disrupting chemicals (EDCs) reported to alter thyroid function. Iodide uptake by thyroid follicular cells, an early step in the synthesis of thyroid hormones, is a potential target for thyroid disruption by EDCs. The aim of the present study was to evaluate the acute effects of perfluorooctane sulfonic acid (PFOS) and perfluorooctane carboxylic acid (PFOA), two of the most abundant PFAS in the environment, on iodide transport by thyroid follicular cells in vitro. Dynamic changes in intracellular iodide concentration were monitored by live cell imaging using YFP-H148Q/I152, a genetically encoded fluorescent iodide biosensor. PFOS, but not PFOA, acutely and reversibly inhibited iodide accumulation by FRTL-5 thyrocytes, as well as by HEK-293 cells transiently expressing the Sodium Iodide Symporter (NIS). PFOS prevented NIS-mediated iodide uptake and reduced intracellular iodide concentration in iodide-containing cells, mimicking the effect of the NIS inhibitor perchlorate. PFOS did not affect iodide efflux from thyroid cells. The results of this study suggest that disruption of iodide homeostasis in thyroid cells may be a potential mechanism for anti-thyroid health effects of PFOS. The study also confirms the utility of the YFP-H148Q/I152 cell-based assay to screen environmental PFAS, and other EDCs, for anti-thyroid activity.

Removal and sequestration of iodide using silver-impregnated activated carbon

Two silver-impregnated activated carbons (SIACs) (0.05 and 1.05 wt % silver) and their virgin (i.e., unimpregnated) granular activated carbon (GAC) precursors were investigated for their ability to remove and sequester iodide from aqueous solutions in a series of batch sorption and leaching experiments. Silver content, total iodide concentration, and pH were the factors controlling the removal mechanisms of iodide. Iodide uptake increased with decreasing pH for both SIMS and their virgin GACs. The 0.05% SIAC behaved similarly to its virgin GAC in all experimental conditions because of its low silver content. At pH values of 7 and 8 there was a marked increased in iodide removal for the 1.05% SIAC over that of its virgin GAC, while their performances were similar at a pH of 5. Scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) analyses prior to reaction with iodide showed the presence of metallic silver agglomerates on the 1.05% SIAC surface. After the reaction, elemental mapping with EDX showed the formation of silver iodide agglomerates. Oxidation of metallic silver was observed in the presence of oxygen, and the carbon surface appears to catalyze this reaction. When the molar ratio of silver to iodide was greater than 1 (i.e., M-Ag,M-SIAC > M-I,M-TOTAL), precipitation of silver iodide was the dominant removal mechanism. However, unreacted silver leached into solution with decreasing pH while iodide leaching did not occur. When MAg,SIAC M-I,M-TOTAL, silver iodide precipitation occurred until all available silver had reacted, and additional iodide was removed from solution by pH-dependent adsorption to the GAC. Under this condition, silver leaching did not occur while iodide leaching increased with increasing pH.

The carbon/iodide interface in protic ionic liquid medium for application in supercapacitors

Organic and inorganic iodides dissolved in protic ionic liquid (PIL) were used as source of pseudocapacitance at the activated carbon (AC) electrode/electrolyte interface. The organic iodide solutions were 0.25 mol.L-1 triethylammonium (protic) or tetraethylammonium (aprotic) iodide in triethylammonium bis(trifluoromethane) sulfonimide (PIL) and the inorganic ones 0.2 mol.L-1 potassium or lithium iodides in the same PIL. Experiments in two-electrode AC/AC cells with a silver pseudo-reference electrode demonstrate that the carbon/iodide interface in PIL undergoes redox reactions at around +0.6 V vs. Ag at the positive electrode whatever the iodide solution. The best capacitance properties were given by the KI solution, which allows operating up to 2.0 V with high capacitance value of 189 F.g(-1) and 95% efficiency. Adding organic iodides to PIL resulted in a decrease of voltage from 2.4 V to 1.5 V, but still high capacitance values of 164 F.g(-1) and 151 F.g(-1) were observed for the protic and aprotic iodides, respectively.

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.

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.
