[5,10,15,20-Tetrakis(4-N,N-dimethylaminobenzene)porphyrinato]Mn(III) acetate (MnTDPAc) was applied as an ionophore for an iodide-selective PVC membrane electrode. The influences of the membrane composition, pH of the test solution and foreign ions on the electrode performance were investigated. The sensor exhibited not only excellent selectivity to iodide ion compared to Cl- and lipophilic anio...

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...

In the course of biological screening for herbicidal activity in synthetic compounds, various organic iodide complexes had marked defoliating properties when applied to leguminous test plants. Simple iodides such as the salts of alkali metals also caused defoliation. Although this effect has been reported in the patent literature (4, 8), our present investigation was undertaken principally to l...

Based on a unique elimination reaction prompted by the iodide ion, a novel turn-on fluorescence probe (HCy-OMe-Br) has been developed for the first time. The probe emits in the near infrared region with a large Stokes shift, and can respond rapidly to iodide with high selectivity and sensitivity.

In this study, the reaction between Co(III)-EDTA and hypophosphite ion, catalyzed by Pd(II), was chosen as the indicator reaction. The inhibition kinetics of this catalytic reaction were investigated in the presence of iodide ion and the possibility of its analytical application was evaluated. Catalyzers other than PdCl2 (Pt, Au and Ni salts) were assayed for the indicator reaction and it was o...

The structures of the solvated zinc ion and the solvated zinc-iodide complexes in methanol solution have been determined by EXAFS. The zinc ion is six-coordinated in an octahedral fashion with a mean Zn-O bond distance of 2.071(4) Å. According to the stability constants of the zinc-iodide system in methanol solution the first complex, ZnI+, is suppressed, which may indicate that a coordination ...

Using molecular dynamics simulations in an explicit aqueous solvent, we examine the binding of fluoride versus iodide to a spherical macromolecule with both hydrophobic and positively charged patches. Rationalizing our observations, we divide the ion association interaction into two mechanisms: (1) poorly solvated iodide ions are attracted to hydrophobic surface patches, while (2) the strongly ...

When iodides are administered in ordinary doses excretion takes place rapidly. Heavy doses can usually be administered before toxic symptoms develop. The same is true to an even greater extent of bromides. The bromide ion appears to be capable of replacing the chloride ion to a Considerable degree in the body fluid of mammals without the production of distinct toxic symptoms. Thus Frey (1910--1...
