ferric ferrocyanide การใช้

• These two pigments are chromium oxide greens / ferric ferrocyanide, or Prussian blue.
• The result is an insoluble, blue dye ( ferric ferrocyanide ) known as Prussian blue.
• After heating the resulting solid to an ash, filtering and diluting, Diesbach added green vitriol ( iron sulphate ) to create a complex ion : ferric ferrocyanide.
• Ferric iron deposits in tissue ( present mostly as ferric iron within the storage protein ferritin ) then react with the soluble ferrocyanide in the stain, to form insoluble Prussian blue dye ( a complex hydrated ferric ferrocyanide substance ) " in situ " ( i . e ., in place ).
