Get Price- Can ferrate be used for water treatment?
- Ferrate is emerging as a green chemical for organic synthesis and for treating toxins in water. This review paper aims to discuss the potential of generating ferrate (VI) in situ and using it for water treatment. The first part provides a short review of recent advances in Fe (VI) synthesis and introduces its in situ electrochemical synthesis.
- Can ferrate (VI) be electrochemically produced in situ?
- Furthermore, ferrate (VI) can be electrochemically produced in situ using high-oxygen overpotential anodes, such as boron-doped diamond electrodes, under circumneutral conditions, enabling simultaneous Fe (VI) synthesis and water treatment within a single electrochemical reactor.
- Can ferrate (VI) be used in water and wastewater treatment?
- Here we argue that five technical barriers prevent the water industry from establishing the necessary credibility for the full-scale application of ferrate (VI) in water and wastewater treatment. (1) Challenges of Ferrate (VI) Synthesis. The bottleneck for ferrate (VI) application is the lack of practical synthesis devices.
- Can ferrate (VI) reshape the conventional water treatment paradigm?
- Consequently, while the way ferrate (VI) is simply used enhances a particular treatment performance, it cannot develop a standalone, one-step ferrate (VI) treatment system to reshape the conventional water treatment paradigm by steering the multifunctional potential of ferrate (VI) within a single reactor.
