Reinhart © 2008 Gianna Griffith Cooley ii ABSTRACT VI 2- Ferrate (molecular formula, Fe O4 ) has been studied increasingly since the 1970s as a disinfectant and coagulant for domestic wastewater and also as an oxidant for industrial wastewaters (Murmann and Roginson, 1974, Gilbert et al., 1978, Kazama, 1994, Jiang et al., 2002, and Sharmaet al., 2005). This research was performed to explore whether ferrate could possibly be used as chemical treatment for industrial wastewaters from plastic, chemical, dye, soap, and wood stain producing plants that contain 2, 4-Dinitrophenol (DNP).

Lanthanum barium ferrates have auspicious properties as triple conducting oxides (proton-, oxygen ion- and electron-conducting) and therefore are promising new materials for future applications in protonic ceramic fuel cells, electrolyser cells or membranes for hydrogen separation [1]. However, mass and charge transport as well as defect chemistry are only partially understood at this point. These properties are influenced by the

Box 17011, Johannesburg, South Africa, 2028 Graphical Abstract Investigation into the production, characterization and application of ferrate(VI) in water and wastewater treatment to enable metal removal through oxidation and coagulation processes and recommended in perspective for AMD treatment as a sustainable process. This paper aimed at reviewing different research work done on the synthesis of ferrate(VI) salts of potassium and or sodium, their applications in industrial wastewater, municipal sewage and water treatment. In this review, it was found that ferrate(VI) salt can exhibit more than one function in water and wastewater treatment as this chemical can take the roles of coagulants, flocculants, antioxidant, bactericide or disinfectant, and oxidant. Despite these properties, its availability on the market in a solid state is still a big problem due to its high cost and difficulties during its production as well as its chemical instability. Furthermore, suitable methods or procedures for manufacturing pure and stable ferrate(VI) salts were established in the past decades but are too expensive to produce sufficient quantities required for a large-scale water and wastewater treatment. Current ferrate synthesis methods include wet chemical oxidation, dry and electrochemical techniques. Among them, the wet oxidation method is the most applicable and safe to generate ferrate(VI) as dry and electrochemical methods can provoke detonation due to elevated temperatures and high concentration of electrolytes used, respectively.

Abstract VI 2 Recently, the tetraoxy high-valent iron(VI), known as ferrate(VI) (Fe(VI); Fe O4 ), received a great attention as a water-treatment chemical, because of its unique oxidation, disinfection, and coagulation properties. Though Fe(VI) has shown remarkable efficiency in oxidizing several pollutants in water, it has sluggish reactivity with some emerging organic contaminants, especially at basic pH conditions. Thus, the main objective of this PhD thesis was to activate or catalyze Fe(VI) oxidation reactions, at mild alkaline pH conditions, to enhance the oxidative transformation of organic pollutants and reduce the required dosage of Fe(VI) and contact time.

BaFe nanoparticles were labeled using a hydrothermal Ba2+ cations replacement by 223Ra with yield reaching 61.3 1.8%. Radiolabeled nanoparticles were functionalized ± with 3-phosphonopropionic acid (CEPA) linker followed by covalent conjugation to trastuzumab (Herceptin®). Thermogravimetric analysis and radiometric method with the use of [131I]-labeled trastuzumab revealed that on average 19–21 molecules of trastuzumab are attached to the surface of one BaFe–CEPA nanoparticle.

Box: 101110, Georgetown, Guyana Keywords: Ferrate (VI) technology, potassium ferrate, barium ferrate, green chemical, wastewater treatment. ABSTRACT The ferrate (VI) a green chemical due its novel properties such a oxidizing power, selective reactivity, stability as salt and non-toxic by-products of ferric ion, much progress has been made on its application to water and wastewater treatment as efficient oxidant, coagulant and disinfectant. Potassium and barium ferrate are synthesized, purified and characterized. These two chemicals were used to treatment of water samples collected from Guyana Water Incorporation Georgetown (GWI Georgetown), Guyana Water Incorporation Linden (GWI Linden), Tap water South Ruimveldt (Tap Water SR) and University of Guyana Pond (UG Pond).

  • Mechanism of Thermal Decomposition of K2feo4 and Bafeo4:Areview
    Hyperfine Interact (2016) 237:128 DOI 10.1007/s10751-016-1338-x Mechanism of thermal decomposition of K2FeO4 and BaFeO4:Areview Virender K. Sharma1,2 · Libor Machala2 © Springer International Publishing Switzerland 2016 Abstract This paper presents thermal decomposition of potassium ferrate(VI) (K2FeO4) and barium ferrate(VI) (BaFeO4) in air and nitrogen atmosphere. Mossbauer¨ spectroscopy and nuclear forward scattering (NFS) synchrotron radiation approaches are reviewed to advance understanding of electron-transfer processes involved in reduction of ferrate(VI) to Fe(III) phases. Direct evidences of FeV and FeIV as intermediate iron species using the V IV applied techniques are given. Thermal decomposition of K2FeO4 involved Fe ,Fe ,and IV K3FeO3 as intermediate species while BaFeO3 (i.e. Fe ) was the only intermediate species during the decomposition of BaFeO4. Nature of ferrite species, formed as final Fe(III) species, of thermal decomposition of K2FeO4 and BaFeO4 under different conditions are evaluated. Steps of the mechanisms of thermal decomposition of ferrate(VI), which reason- ably explained experimental observations of applied approaches in conjunction with thermal and surface techniques, are summarized.
