    Preparation. ferricyanide is manufactured by passing chlorine through a solutions . ferricyanide separates from the solution: 2K 4 [FeCN 6] + Cl 2 → 2K 3 [FeCN 6] + 2KCl Applications. The compound has widespread in blueprint drawing and in photography Cyanotype

  • Potassium Ferrocyanide uses in photography?

     · One gram Ferricyanide Anhydrous can also be obtained by mixing 0.41 gram persulfate and 1.47 grams of sodium decahydrate. The reaction between persulfate and sodium takes about 1 hour, after which the final adjust ments to the mix should be made

  • In Situ Generation of Prussian Blue with Potassium

    Using magnetic nanoparticles MNPs as a label in immunoassay IA possesses advantages such as high specific surface area, simple modification . However, the catalytic activity of MNPs is low, which limits their applications in IA. The present study found it interesting that reacts with MNPs, leading to the in situ generation of Prussian blue. The produced
