This time, a section of the chapter has been dedicated to this oxide so that you can learn how it behaves in different physical and chemical conditions. The chemical formula of Iron III oxide is Fe2O3. It is obtained from a mineral ore called hematite. It is mined and then processed t...

Chemical-looping combustion (CLC) is a combustion technology with inherent separation of the greenhouse gas CO2. The technique involves the use of a metal oxide as an oxygen carrier that transfers oxygen from the combustion air to the fuel. The use of iron oxide as an oxygen carrier has been...
In this paper, a novel biocompatible magnetic iron oxide nanoparticles/hydrogel was synthesized based on the simultaneous formation of magnetic iron oxide nanoparticles (MION) and hydrogel based on poly (acrylic acid) grafted onto starch (PAA-g-starch). The structural, morphological and magnetic prope...
This is reported in some Superior, Rapitan and Ediacaran BIFs, in particular where the main dominant oxide facies is hematite. Also, the mixing of oxygen-rich water from the ice thawing with oxygen-depleted exhalative hydrothermal fluids (Fig. 25c, d) may be considered as another mechanism to...
Textile effluents contain dyes that negatively affect water bodies and inhibit photosynthesis by reducing sunlight penetration. This study investigated the adsorption capacity of an iron oxide sorbent immobilised on naturally derived carbon foam for the
a diffusion process, except for the slow reaction of Pb adsorption on the Fe oxides formed at the initial citrate/Fe(II) MR of 0.1, where the rate-limiting process was evidently a chemical process, which may involve bond breaking between the coprecipitated citrate ligand and Fe oxide. The...
The dissolution rate coefficients are determined as a function of the Cr content of the oxide and reagent concentration of the CEA mixture, using a general kinetic equation. The dissolution rate coefficients are found to decrease with increase in chromium content of hematite and magnetites. The Cr...
The grafting density was estimated using the weight loss (loss-wt) and the surface area of IONPs determined by BET according to the following equation: Mnpolymer corresponds to the weight of polymer grafted. Na is Avogadro’s number and mNP is the mass of polymer-grafted iron oxide ...
