According to Harington, two fractions, one “thyroxine-like” and the other “diiodotyrosine-like,” can account for all of the organic iodine found in the thyroid gland (1). The metabolism of these compounds has been reviewed recently by Salter (2). The labeling of iodine by radioactivity provides for the first time a desirable tool for the study of the endogenous or normal rates of formation of t...

An inductively coupled plasma mass spectrometer (ICP-MS) was used as an ion chromatographic detector for the speciation of iodine and bromine. Gradient elution using NH4NO3 at pH 10 allowed the chromatographic separation of ionic iodine (I- and IO3-) and bromine (Br- and BrO3-) species in less than 8 min. Effluents from the ion-exchange column were delivered to the nebulization system of ICP-MS...

The recovery of iodine released during the processing of used nuclear fuel poses a significant challenge to the transmutation of radioactive iodine. This proposal will develop and examine the use of Fullerene Containing Carbon (FCC) compounds as potential sorbents for iodine release from the reprocessing of nuclear fuel. This work will also include the development of bench-scale testing capabil...

The literature on the relation of iodine to the thyroid gland is extensive, and a comprehensive review of it is not presented in this paper. Excellent reviews exist. The older literature has been reviewed by Horsley (1), the more recent by Wells (2), Marine (3) and Rost (4). Reference will be made only to those observations relevant to the particular problem under consideration. It is now gener...

Four different nitroimidazole derivatives, with up to two iodine atoms on the imidazole ring, were investigated for their radiosensitizing potency under hypoxic conditions, in order to test whether the introduction of iodine atoms increases the radiosensitizing potency of nitroimidazoles. Misonidazole and metronidazole were used as controls. Human colonic adenocarcinoma cells were incubated wit...

The condensation polymer derived from reaction between titanocene dichloride and 2-nitro-1,4-phenylenediamine was doped by mixing the polymer with different amounts of iodine. This bulk doping of the titanocene polyamine resulted in an increase in bulk conductivity from 10 to over 1,000 fold. Conductivity increased to a doping level of about 10 to 15% iodine. Conductivity decreased as the sampl...

Individual and simultaneous electrochemical detection of iodide and iodine has been performed via cyclic voltammetry on boron doped diamond (BDD) electrodes in a 1M NaClO(4) (pH 8) solution, representative of typical environmental water conditions. It is feasible to compute accurate calibration curve for both compounds using cyclic voltammetry measurements by determining the peak current intens...

Around the world, maize cultivation is an essential part of food systems for humans and animals. Effective reactions against occurrence diseases related to deficiency elements in human diet are biofortification plant species broad importance, including maize. The enrichment with iodine difficult due poor transport this element plant’s generative organs. In marine algae, vanadium structure enzym...
