Determination of ferrous and ferric iron from total iron content and thermogravimetric analysis

Ferrous ( Fe 2 + ) and ferric ( Fe 3 + ) iron content in mineral samples was determined from total iron (as obtained, for instance, from X-ray fluorescence analysis) and mass increase upon switching the purge gas from inert to oxidizing, at high temperature, in a thermogravimetric analysis. The meth...
