Kinetic-spectrophotometric method for the determination of trace amounts of bromide in seawater [PDF]
, 2005 A novel simple, sensitive and rapid kinetic-spectrophotornetric method is proposed for the determination of trace amounts of bromide. The method is based on its catalytic effect on the oxidation of methylene blue (MB) by hydrogen peroxide in strongly ...

Scalable synthesis of ionic liquids: comparison of performances of microstructured and stirred batch reactors [PDF]
, 2012 A range of alkylpyridinium bromide ionic liquids have been synthesized in a stirred reactor at multigram scale and characterized by physical methods (viscosity, conductivity, melting point, electrochemical window, and water content).

SANS studies of liquid crystalline microemulsion gels [PDF]
, 1989 We have investigated by small-angle neutron scattering (SANS) the ternary system containing water, alkane and the surfactant mixture benzyltetradecyldimethylammonium chloride and tetradecyltrimethylammonium bromide, which we have found to form a cubic ...

Intramolecular pi-pi stacking interactions in 2-substituted N,N-dibenzylaziridinium ions and their regioselectivity in nucleophilic ring-opening reactions [PDF]
, 2009 The ring opening of 2-substituted N,N-dibenzylaziridinium ions by bromide is known to occur exclusively at the Substituted aziridine carbon atom via ail S(N)2 mechanism, whereas the opposite regioselectivity has been observed as the main pathway for ring

Oxidation of Cr(III)-Fe(III) Mixed-Phase Hydroxides by Chlorine: Implications on the Control of Hexavalent Chromium in Drinking Water. [PDF]
, 2018 The occurrence of chromium (Cr) as an inorganic contaminant in drinking water is widely reported. One source of Cr is its accumulation in iron-containing corrosion scales of drinking water distribution systems as Cr(III)-Fe(III) hydroxide, that is, Fe ...

Atmospheric residence time of CH3Br estimated from the junge spatial variability relation [PDF]
, 1998 The atmospheric residence time for methyl bromide (CH3Br) has been estimated as 0.8 +/- 0.1 years from its empirical spatial variability relative to C2H6, C2Cl4, CHCl3, and CH3Cl.

Determination of extracellular fluid volume in healthy and azotemic cats [PDF]
, 2015 BACKGROUND: Methods for determining extracellular fluid volume (ECFV) are important clinically for cats. Bromide dilution has been studied in cats to estimate ECFV. Markers of GFR also distribute in ECFV and can be used for its measurement.
