Abstract
Mn(II) was quantitatively preoxidized to MnO4- and then spectrophotome trically determined at 527 nm. The interference of Fe(III) was studied during this determination. The analysis of variance was used to test the significance of Fe(III) and H3PO4. The problem of the interference of Fe(III) in two materials, steel and ferrite (Fe, Mn, Zn) was also studied. Our results demonstrated that Fe(III), up to 300-fold the amo unt of Mn, does not interfere.
