Potentiometric determination of hydrogen peroxide with permanganate in presence of fluoride, with iron as a catalyst: Application to the titanium-fluoride-peroxide mixed complex

L P Diez et al. Talanta. 1981 Dec.

Abstract

A potentiometric permanganate titration has been developed for the determination of hydrogen peroxide in the presence of fluoride, as well as of the peroxide content in the titanium-fluoride-peroxide mixed complex. It is based on the stabilization of manganese(III) with an excess of fluoride in a moderately acidic medium (pH close to 3) and on the use of iron(III) as catalyst. Errors are less than 0.5%.
