5, 100, 500 g in poly bottle

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.

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.
