Electrocatalytic oxidation
of 2,4,5,7-tetrabromofluorescein and 2,7-diclorofluorescein by oxygen adsorbed
on platinum
Abstract
The oxidation of 2,4,5,7 –
tetrabromofluorescein and 2,7 diclorofluorescein on platinized platinum in
alkaline medium was studied. All adsorbed substances had oxidized at the lower
potentials, than that of oxygen evolution. The chromatography-mass spectrometry
was realized to determine products of oxidation 2,7 diclorofluorescein at
cycling potential and at oxygen evolution. It was shown that content of
phthalate in products of oxidation 2,7 diclorofluorescein was about 0,31% at
cycling potential when for oxidation at oxygen evolution this value was 25%.
