The GC of halides (chloride, bromide and iodide) using phenylboronic acid (PBA), 4-bromophenylboronic acid (BPBA), 3, 5 bis (trifluoromethyl) phenylboronic acid (FPBA) and 2,4- dichlorophenylboronic acid (CPBA) as derivatizing reagents are compared. The reactions are carried out in the presence of mercuric salts. The detection systems used are FID and ECD. The thermal analysis of the compou...

Sodium iodide was given in increasing doses to mentally defective children with normal thyroid function. Maximal suppression of iodine-131 uptake was achieved with 1500 to 2000 micrograms of iodide per square meter of body surface per day, but quickly rebounded when iodide was discontinued. This minimal effective dose is important if countermeasures against fallout are employed.

The dilution controlled aggregation enhanced emission of spherically aggregated form of a triazole based probe dies down upon detecting iodide over other inorganic anions. The sensing is realised as a dynamic quenching mechanism dominated event. Being highly selective for iodide, the probe finds application in the detection of iodide in human urine.

A sensitive assay is developed to assess the existence of an iodide channel in a fraction of solubilized membrane proteins. This step is critical when considering various procedures for purification of this channel. Sodium cholate is used as a detergent as it does not denature the iodide channel. A simple and rapid method involving gel-filtration chromatography is used simultaneously to remove ...

Binding of an iodide ion to horseradish peroxidase was studied by following the hyperfine-shifted proton nuclear magnetic resonance signals of the enzyme. For the enzyme in an iodide-free solution, the spectra of hyperfine-shifted methyl region were only slightly affected by varying pH. In the presence of iodide (200 mM), however, both chemical shifts and line widths of the heme peripheral 1- a...

BACKGROUND Perchlorate and thiocyanate interfere with iodide uptake at the sodium-iodide symporter and are potential disruptors of thyroid hormone synthesis. Perchlorate is a common contaminant of water, food, and human milk. Although it is known that iodide undergoes significant diurnal variations in serum and urinary excretion, less is known about diurnal variations of milk iodide levels. O...

The sorption affinity of iodide on organo-bentonite, modified with hexadecyl pyridinium (HDPy), was investigated the iodine–starch method coupled UV/Vis absorption spectroscopy. complex optimized in terms reaction time and sample compositions, based absorbance. batch experiment for organo-bentonites, using two different loading amounts HDPy, conducted to analyze influence equilibrium time, liqu...
