General description
Potassium ferricyanide(III) is a potassium salt widely employed as an external indicator in potassium dichromate titrations. A sensor containing potassium ferricyanide assisted enzyme electrode for estimating maltose and glucose in samples has been reported. Addition of potassium ferricyanide in the catholyte can improve the generation of power in microbial fuel cells (MFCs).
Application
Potassium ferricyanide(III) has been used:
- To prepare the X-gal staining solution for staining cryosectioned tissues of injured neonatal mouse heart.
- Reducing power assay of freeze-dried ethanolic extract of Issopus officinalis.
- In combination with glutaraldehyde and osmium tetroxide for post-fixation of biological samples prior to epoxy embedding.
