Reaction of ferrate is typically fast, producing non-toxic by-products. The stable decomposition product of ferrate is iron in either the +2 or +3 oxidation state, providing the coagulation function. Ferric and ferrous ions are used widely as coagulants to remove suspended solid from aqueous system.
ENVIFER is suitable for elimination of many organic and inorganic micro pollutants. The advantages are rapid reaction with contaminants and low reagent consumption. In addition, ferrates have also a disinfection capacity as they can easily reduce various microorganisms (Cryptoporidium, coliforms, salmonella, etc.).
Remarkable efficiency of phosphate removal: Ferrate(VI)-induced in situ sorption on core-shell nanoparticles
Despite the importance of phosphorus as a nutrient for humans and its role in ecological sustainability, its high abundance, resulting in large part from human activities, causes eutrophication that negatively affects the environment and public health. Here, we present the use of ferrate(VI) as an alternative agent for removing phosphorus from aqueous media. We address the mechanism of phosphate removal as a function of the Fe/P mass ratio and the pH value of the solution.
Use of the ferrates (FeIV-VI) in combination with hydrogen peroxide for rapid and effective remediation of water
This study is focused on laboratory experiments using industrial groundwater leading to the proposal of a pilot field application realized as an ex-situ remediation. The combination of ferrates with hydrogen peroxide was used in this study in order to enhance the removal efficiency during pilot remediation of groundwater strongly contaminated by a wide range of organic contaminants. This combination has been shown to be very effective. During the 24-hour reaction time the majority of detected contaminants were removed by approximately 60-80%.
