A novel Fenton-like system of Fe2O3 and

02.01.2020· A new Fenton-like catalysis system consisting of Fe 2 O 3 and NaHSO 3 was designed, tested and established as a catalyst for the degradation of Orange II dye. The results of the degradation showed that the treatment efficiency was considerable under different conditions but with a significant increase under alkaline or strongly alkaline conditions compared to that under the acidic condition.

Re: Calculation FeO total to "FeO and Fe2O3" or

Could I get the FeO and O2 value from the equation "FeO total = FeO + 0.8998*Fe2O3" or molar stoichiometric equation Fe2O3 = 0.5O2 + 2FeO? It is a dumb question, but I think it is important to know the stoichiometric calculation of FeO and Fe2O3 separation. Thank you for read. I would be greateful if I could get advice on that.

Separating Fe into FeO & Fe2O3

12.11.2014· You can get a good standard by oxidising a pure iron standard. Mostly FeO then Fe3O4 then a thin layer of Fe2O3. Trouble is, the FeO varies from one side to the other of the wustite phase. If there is Mn in the steel, you get a fascinating pile up rejection in the wustite at the magnetite boundary as it flees the higher oxidation states.
