We present an electrochemical advanced oxidation process (eAOP) reactor employing expanded graphite, potassium iodide (KI), and electrical current, which demonstrates exceptionally high rate of inactivation Escherichia coli (106 or 6 log10 reduction in viable cells) at a low current density (0.12 mA/cm2), with short contact time (5 min) concentration KI (10 ppm, 0.06 mM). Advanced spectroscopic...

sodium iodide-131 is administrated for treatment of hyperthyroidism and thyroid cancer. iodine-131 has multiple routs of excretion (urine, saliva, sweat, milk, feces, exhalation) from the body. patients receiving sodium iodide-131 therapy exposes other persons and the environment to unwanted radiation and contamination. the major source of radiation dose from administration of iodine-131 is ext...

In 1932 (1) the author published a method for determining methionine in proteins based on the recovery of methyl iodide. Alcoholic silver nitrate was used as absorbant and the excess of silver nitrate was titrated with thiocyanate after filtering off the silver iodide. This method was quite satisfactory and has been used recently by Barritt (2) for the determination of methionine in wool. Certa...

Iodine, chiefly as iodide, has long been employed in the treatment of leprosy, with varying results. Its use previous to 1911 was reviewed by Currie, Clegg, and Hollmann (1 ). The iodides had been largely abandoned as of no value or as apt to cause aggravation of the disease, but potassium iodide was reintroduced by Muir, partly for its supposed " lepromalytic" action and antigenic effect, part...

Although iodization of salt is the most common method used to obtain iodine-enriched food, iodine deficiency disorders are still a global health problem and profoundly affect the quality of human life. Iodine is required for the synthesis of thyroid hormones, which are crucial regulators of human metabolism, cell growth, proliferation, apoptosis and have been reported to be involved in carcinog...

Iodine deficiency during pregnancy and lactation could expose the infant to severe iodine deficiency disorders. A randomized supplementation trial among rural lactating women was conducted in Sidama zone, southern Ethiopia, to compare the methods of iodine delivery on breast milk iodine, and on maternal and infant urinary iodine concentrations. Women were randomly assigned either to receive 225...

Methyl iodide is a well-known volatile halogenated organic compound that contributes to the iodine content in the troposphere, potentially resulting in damage to the ozone layer. Most methyl iodide sources derive from biological activity in oceans and soils with very few abiotic mechanisms proposed in the literature. In this study we report that synthetic manganese oxide (birnessite δ-MnO2) can...

We propose an automated method for the routine analysis of urinary iodide, using paired-ion reversed-phase HPLC with electrochemical detection and a silver working electrode. Assay conditions include a flow rate of 1.0 mL/min and an operating potential of 0.10 V. The retention time for iodide is 5.4 min. Sample preparation can be semiautomated by use of a reduced-pressure manifold. The detectio...

In normal rats maintained on an adequate iodine intake, the iodine concentration in the thyroid gland is about 10,000 times as great as that in plasma, a finding that illustrates the remarkable iodine-concentrating capacity of this tissue (1). The fact that almost all of the iodine in the normal gland is organically bound (2, 3) would suggest that this concentrating capacity is dependent upon t...

In Aurelia aurita, applied iodine induces medusa formation (strobilation). This process also occurs when the temperature is lowered. This was found to increase oxidative stress resulting in an increased production of iodine from iodide. One polyp produces several medusae (initially termed ephyrae) starting at the polyp's oral end. The spreading of strobilation down the body column is controlled...
