FeO determination in rocks and minerals by wet chemistry
FeO determination in rocks and minerals by wet chemistry Introduction Most analytical techniques used for rocks and minerals cannot distinguish between the oxidation states of different chemical elements, including iron. Because of its abundance, the redox state of iron can be particularly important. The iron in common rocks is in the Fe2+andfe2o3 feo and fe3o4 analysis in iron ore,FeO determination in rocks and minerals by wet chemistry. redox state of iron can be particularly important. The iron in common rocks is in the Fe2+and Fe3+states, usually present in minerals as the nominal chemical components FeO and Fe 2 O 3, respectively. The analytical procedure described here permits the analysis of FeO in a sample by titration. How it works 1.Techniques for Collectors : FeOtot recalculation to FeO,,16.03.2011· The wet analysis is impossible for mixed, altered or too small minerals. You may avoid undetermined elements by using LA-ICP-MS, sometimes just this helps to get the formula. Sometimes the structure can help, eg. if you can say there is no Fe in position typical for Fe3+ - Raman and IR spectroscopy or xray diffraction help with this. The most efficient method is to use MossbauerOptimizing the Pratt-type titrimetric method to determine,,wet chemical analyses, titrimetric methods are one of the most classical methods used to measure FeO values. Al-though titrimetric methods yield accurate FeO values, it is time consuming. Much progress has been made on measuring FeO using analytical instruments; this includes new methods such ion chromatography (Kanai, 1990; leESTIMATION OF IRON (Fe) BY WET CHEMICAL METHOD IN,Food Testing & Analysis.

The reason for this is that FeO is very easily oxidised during the typical sample dissolution stage.
