Green rust (GR) is an intermediate product during the process of iron corrosion. Due to its special kind of layered structure, it can easily exchange anions from its gallery part, and can be used in water treatment. It also has the ability to incorporate cations in the gallery. In addition, several hazardous cations can be adsorbed and finally bonded to the hydroxide part, or replace the iron cations in the crystal lattice, and be captured. All these properties lead GR to be efficiently advantageous for water purification applications. In this article, we provide an overview and literature survey on electrochemical generation of GR and modified GR, and their applications for water treatment.

Keywords: Adsorption, anions, electrochemistry, green rust, intercalation, ion exchange, layered double hydroxides, metal ions, reduction, surface ground water, water contaminants, water treatment.
