Iron, which is a common metal found in the Earth’s crust. Ferrate(VI) is a strong oxidant which is even stronger than other some common chemicals like permanganate and chromate. Scientists are interested in studying how ferrate reacts with different substances to learn more about its reactivities.

The kinetics for several pollutants and amino acids, including chloride ion, phenols, hydroquinones, ascorbic acid and L-cysteine, with ferrate have been investigated. The rate law, final products of the reactions and the mechanisms have been studied. The discoveries from this research can provide valuable insights into how ferrate reacts with different pollutants. This knowledge can be used to develop and enhance water and wastewater treatment methods. Additionally, by studying the reactions between ferrate and biological molecules, we can gain a better understanding of the underlying mechanisms. This understanding can potentially contribute to the development of new generation medicines, especially anti-cancer drugs.
