High-valent iron species of oxidation states +4, +5, and +6, have been involved as intermediates in enzymatic reactions, in green organic synthesis, and in purification and disinfection of water. Many of these species have been synthesized to understand their role in different systems, which include ferryl complexes (oxoiron(IV) (Fe IV=O), oxoiron(V) (FeV=O)), iron(IV / V / VI)-nitride complexe...

background: application of potassium ferrate is a chemical oxidation approach used for water and wastewater treatment. the aim of this study is to apply central composite design (ccd) and response surface methodology (rsm) to optimize potassium ferrate consumption in the treatment of wastewater from carpet industries. methods: samples in this experimental study were collected from wastewater, o...

The screening and treatment of acid mine drainage (AMD) using Na2FeO4 was explored. Elemental composition performed, an Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) for the raw treated AMD. AMD samples were collected from three different sampling sites:(Raw Tailing Water 1 (RTW1), Raw 2 (RTW2) 3 (RTW3)) in Pretoria, South Africa, with acidic pH ranging between 2.50 3.13. T...

potassium ferrate has been used as a multi-purpose chemical in treatment of wastewaters. with the formula of k2fe04 it has 3 excellent characters for water treatment, so by using it alone, it would be possible to confine all reactivity, it is essential to prepare ferrate at the point of use. in this study, k2fe04 was synthesized, then it has been employed for chlorine gas with an alkaline solut...
