Ferrous sulfate monohydrate CAS:13463-43-9

short description:

Ferrous Sulphate Monohydrate:Sulfate chemical FESO4, commonly, seven crystal water sulfate FESO4 · 7H2O, commonly known as green alum. Light blue -green monocular crystal, density of 1.898g/cm3, chemicalbook64 ℃ melted in crystalline water. Soluble in water, the aqueous solution is acidic. Gradually weathered in the air, and was oxidized into yellow -brown alkaline iron salt. Lost all crystal water at 300 ° C, and the waterless object is white powder.

Main nature: Iron sulfate is easily oxidized into yellow or iron rusty in wet air. In the water, the concentration of the solution for general sulfate is about 10 %. As a concrete, mixed with ChemicalBook Granules, good vegetables, fast sinking, very good coloring effects, low cost of sulfate treatment agents, and suitable for wastewater treatment with PH value above 8.5.

Applications of Ferrous Sulphate Hephydrate

1.Nutritional supplements (iron enhancer); color former of fruit and vegetable; for example, the salted product used together with dried alum in eggplant can form stable complex salt with its pigment to prevent the discoloration caused by organic acids. However, it should be noted, for example, it will turn into black ink upon excess amount of iron. When the amount of alum is high, the meat of the pickled eggplant meat will become excessively solid. Formulation example: long eggplant 300 kg; edible salt 40kg; ferrous sulfate 100g; dried alum 500g. It can still be used as the color forming agent of black beans, sugar boiled beans and kelp. Food containing tannins, in order to avoid of causing blackening, should not be used. It can also be used for sterilization, deodorization and very weakly bactericidal.
2.Legumes contained cryptochromic pigment is colorless upon reduction state while being oxidized into black upon oxidation in alkaline condition. Taking advantage of the reduction property of ferrous sulfate can achieve the purpose of color protection with the usage amount of 0.02% to 0.03%.
3.If is used for the manufacturing of iron salt, iron oxide pigments, mordant, purifying agent, preservatives, disinfectants and medicine for anti-anemia drugs.
4.Ferrous sulfate (FeSO4) is also known as iron sulfate or iron vitriol. It is used in the production of various chemicals, such as sulfur dioxide and sulfuric acid.
5.Ferrous Sulfate is a nutrient and dietary supplement that is a source of iron. it is a white to grayish odorless powder. ferrous sulfate hep- tahydrate contains approximately 20% iron, while ferrous sulfate dried contains approximately 32% iron. it dissolves slowly in water and has high bioavailability. it can cause discoloration and rancidity. it is used for fortification of baking mixes. in the encapsulated form it does not react with lipids in cereal flours. it is used in infant foods, cereals, and pasta products.
6.Iron Supplement.
