Quercetin (3, 3', 4', 5, 7-pentahydroxyflavone) reacts with hexavalent
molybdenum, tungsten and chromium to form chelates soluble
in an ethanol-water medium. This color reaction has been investigated
with a view to its possible application in the spectrophotometric
determination of trace amounts of these metals.
In the development of the method,...
Studies were undertaken to determine the extent and rate of
binding of Hg-203 labeled phenylmercuric acetate and mercuric ace
tate in rat kidney and liver slices and their subcellular fractions
after 37°C incubation of the slices in Krebs-Ringer -phosphate solutions
containing the mercurials at 10⁻⁴ molar. A fast and parallel...
