| Blue dye | Prussian Blue (ferric ferrocyanide) chemical formula Fe4[Fe(CN)6]3, also known as Berlin blue, green blue, iron blue, Milo Blue, Chinese blue, Miro Blue, China Blue. It is an ancient blue dye that can be used for glazing and oil painting. Prussian blue for us is a touching beauty, not only a unique color, but also reflects a precipitation of texture. Prussian blue is a blue dye discovered in 1706. Its structure is composed of Fe (II) and Fe (III) and cyano (-CN-) they are formed by the interaction of coordination. As a kind of coordination polymer, Prussian blue has excellent magnetic, electrical and optical properties, and its magnetic energy is in the range of 200-300K, which conforms to Curie's law. In the field of electrochemistry, Prussian blue is an excellent electron transfer medium. Fe in different valence states in the molecule can transfer electrons through cyano groups, causing two absorption bands at 680nm and 400nm, this is also the reason for the blue color of Prussian blue. Due to the presence of Fe in mixed valence states, Prussian blue also has various redox states and exhibits different colors, such as Prussian White, Berlin Green and Prussian yellow. In particular, the FDA approved Prussian blue as an antidote for thallium and cesium in 2003, which fully demonstrated the good biological safety of Prussian blue and aroused great interest in research, and has made a lot of progress in the biomedical field. |
| Prussian blue cytological staining | Prussian blue is a dye commonly used in histopathology to detect iron and ferritin in tissues. This is a staining technique using histochemical reactions. The principle is the decomposition of protein hydrochloric acid, so that iron and potassium ferrocyanide combined, appear blue. The presence of iron was confirmed when a blue granular substance was observed in the apical cell cytoplasm. Alternatively, the presence of iron can also be confirmed when only macrophages having a rough dark blue substance are collected from a cystic lesion suspected of being of apocrine origin. After Prussian blue staining, the iron was blue and the nucleus was red. The Iron component secreted by apocrine glands is seen in macrophages aspirated from apocrine cysts. |
| preparation method | The yellow blood salt method uses the reaction of potassium salt of yellow blood and ferrous sulfate in slightly acidic solution to form the double salt of ferrous cyanide, then potassium chlorate sulfate is oxidized to form the double salt of iron ferrocyanide and potassium ferrocyanide. If the yellow blood salt sodium is used to make iron blue, the generated double salt should be ammonium instead of sodium, that is, iron ferrocyanide and ammonium ferrocyanide double salt are generated, therefore, according to different raw materials, iron blue is divided into potassium iron blue and ammonium iron blue. The above double salt was filtered, rinsed, dried and pulverized to obtain a dark blue iron blue pigment. |
| Use | dark blue pigment. For paint, ink, painting, crayons, and paint cloth, paint paper, plastic products and other coloring. used in paint, ink, plastic and other industries and cultural materials coloring |
| production method | The Double salt of ferrous ferrocyanide is formed by reacting potassium xanthate with ferrous sulfate in slightly acidic solution, then potassium chlorate sulfate is oxidized to form the double salt of iron ferrocyanide and potassium ferrocyanide. If the yellow blood salt sodium is used to make iron blue, the generated double salt should be ammonium instead of sodium, that is, iron ferrocyanide and ammonium ferrocyanide double salt are generated, therefore, according to different raw materials, iron blue is divided into potassium iron blue and ammonium iron blue. The above double salt was filtered, rinsed, dried and pulverized to obtain a dark blue iron blue pigment. |
