Determination of ferrous and ferric iron from total iron
The quantitative determination of \(\hbox {Fe}^{2+}\) and \(\hbox {Fe}^{3+}\) by thermogravimetric analysis and total iron content (as determined, for instance, from Xray fluorescence analysis) presupposes (1) that the amount of other chemical species that can be oxidized along iron (eg, \(\hbox {Mn}^{2+}\) or carbonaceous residues from the pyrolysis ofAn accurate determination of FeO content is extremely important in chromite ores and refractories made with them The percentage content of FeO and Fe 2 O 3 /FeO ratio in sample is used to solve a whole number of theoretical problems dealing with the mineral composition of chromite spinel, chromite massifs and the degree and nature of the ancient weathering they havedetermination of fe and feo in samples
