Description of Prussian Blue
Prussian blue is a dark blue pigment with the idealized chemical formula Fe 7(CN) 18. To better understand the binding situation in this complex compound the formula can also be written as Fe 4[Fe(CN) 6] 3 · Hx 2O. Another name for the color is Berlin blue or, in painting, Parisian or Paris blue. Turnbull’s blue is the same substance but is made from different reagents, and its slightly different color stems from different impurities.
Prussian blue was the first modern synthetic pigment. It is employed as a very fine colloidal dispersion, as the compound itself is not soluble in water. It is famously complex, owing to the presence of variable amounts of other ions and the sensitive dependence of its appearance on the size of the colloidal particles formed when it is made. The pigment is used in paints, and it is the traditional “blue” in blueprints.
In medicine, Prussian blue is used as an antidote for certain kinds of heavy metal poisoning, e.g., by thallium and radioactive isotopes of cesium. In particular, it was used to absorb 137 Cs+ from those poisoned in the Goiânia accident. Prussian blue is orally administered. The therapy exploits Prussian blue’s ion-exchange properties and high affinity for certain “soft” metal cations.
It is on the World Health Organization’s List of Essential Medicines, the most important medications needed in a basic health system. Prussian blue lent its name to prussic acid (hydrogen cyanide), which was derived from it. In Germany, hydrogen cyanide is called Blausäure (“blue acid”), and Joseph Louis Gay-Lussac gave cyanide its name, from the Greek word kuαvoc (kyanos, “blue”), because of the color of Prussian blue.

What is Prussian Blue?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Prussian Blue which has developed particularly rapidly in recent years. Do you know about Prussian Blue?
The official answer:Prussian Blue (Prussian Blue), or ferrous iron cyanide, with the chemical formula Fe4[Fe(CN)6]3, is a coordination compound that can be used for glazing, as a dye for oil painting, etc.
What’s the application of Prussian Blue?
1.In chemical experiments, the reaction of producing Prussian blue is commonly used to test CN-: FeSO4+ 6NaCN +2Na4[Fe(CN)6]+ 4FeCl3= Fe4[Fe(CN)6]3 ↓ + 12NaCl+ Na2SO4.
In medical treatment, thallium can replace the iron-on Prussian blue to form insoluble substances, so that it is excreted in the feces, for the treatment of acute and chronic thallium poisoning through the mouth has a certain effect. The dosage is generally 250 mg/kg per day, divided into 4 doses, dissolved in 50 mL of 15% mannitol, and given orally.
(Moderate supplementation of potassium chloride, high potassium increases renal clearance of thallium, which may be related to potassium competitively blocking thallium uptake by the renal tubules, while potassium mobilizes intracellular thallium to the extracellular level, increasing blood thallium levels, which can aggravate clinical conditions and therefore should be used with caution.)
2. Dark blue pigment. Used in paints, inks, paintings, crayons, and coloring of painted cloth, lacquered paper, plastic products, etc.
3. Used in paint, ink, plastic, and other industries and the coloring of literature and education supplies
