Analytical quantification of electrochemical ferrates for drinking water treatments

Year: 2016

Type: article

Abstract: Ferrate ions are a highly oxidizing and unstable species that are challenging to quantify and analyze. They are, however, becoming increasingly recognized as an excellent candidate for a number of applications such as for water treatment. A wider acceptance of ferrates requires an accurate assay of the produced ferrates. We report on four analytical methods (existing and new) for quantification of ferrates and discuss their advantages and disadvantages. These methods include titrimetric analysis and spectrometric techniques such as direct colorimetric measurements of ABTS or NaI colorimetric. In terms of accuracy, the cost, simplicity, and time required the modified indirect UV-Vis NaI method is shown to be the most effective of all of the four methods investigated.
