Abstract

The present invention belongs to the field of chemical preparing technology, and is especially direct electrochemical process of preparing ferrate. The preparation process prepares ferrate inside one diaphragm type cylindrical electrolytic bath with pure sodium hydroxide as electrolyte. While controlling electrolyte concentration, reaction temperature and applied voltage, high concentration sodium ferrate solution is first prepared, and potassium ferrate or barium ferrate is then prepared via adding potassium ion or barium ion. The present invention has simple technological process and low cost, and is suitable for large scale preparation of ferrate.

Description

technical field [0001] The invention belongs to the technical field of medicament preparation technology, and in particular relates to a method for directly electrochemically preparing ferrate. Background technique [0002] Ferrate refers to hexavalent iron compound and is the only stable high-valent iron compound. Owing to the many unique properties of ferrate, it has received increasing attention in various applications in recent years. First of all, ferrate has strong oxidizing properties, and the final product of the reaction with organic matter is non-toxic and harmless ferric ions. It can be used as a multifunctional green water treatment chemical agent integrating oxidation, flocculation, sterilization and disinfection; Not only that, the super iron battery with ferrate as the cathode material is very attractive for its large capacity, good chargeability, strong conductivity, and environmental friendliness; in organic synthesis, ferrate has the characteristics of sel...
