General description
Potassium hexacyanoferrate(II) trihydrate, commonly known as potassium ferrocyanide, is a commonly used anticaking agent. Its cytotoxic and genotoxic effect has been evaluated. The growth of chemical garden in aqueous potassium hexacyanoferrate solution droplets on a superhydrophobic surface has been reported. The inhibition efficiency of potassium ferrocyanide in phosphoric acid solution against the corrosion of mild steel has been investigated.
Application
Potassium hexacyanoferrate(II) trihydrate may be used in the following processes:
• Preparation of Carrez I solution.
• Milk sample preparation for gold nanoparticles (AuNPs) based colorimetric detection of melamine.
• Preparation of ferrocyanide/ferricyanide reaction, a redox pair solution for electrochemical testing.
