What is Ferrous Sulfate Heptahydrate?
The chemical formula of ferrous sulfate is FeSO4, and the typical one is ferrous sulfate FeSO4 · 7H2O including seven crystal waters, typically referred to as green hostility. Light turquoise monoclinic crystal, density 1.898 g/cm3, soluble in crystal water at 64 ° C. Soluble in water, the aqueous remedy is acidic. Slowly weathered in the air, while being oxidized to yellow-brown basic iron salt. At 300 ° C, all crystallization water is shed, as well as the anhydrous is a white powder.
Ferrous sulfate is conveniently oxidized right into yellow or rust color in moist air. Soluble in water, typically the focus of ferrous sulfate service has to do with 10%. As a coagulant, it has large coagulation fragments, excellent vegetable water residential or commercial properties, quick sedimentation, excellent decolorization effect, affordable of ferrous sulfate treatment representative, and is suitable for wastewater treatment with a pH value over 8.5.
When utilizing it, it is prepared right into a 5%-10% liquid remedy and afterwards included in the raw water. The pH value of the raw water is adjusted to 9-11 with lime, as well as the impact is a lot more suitable. Benefits of ferrous sulfate heptahydrate: low-cost cost, great decolorization result, huge flocculation alum, and settlement. Under acidic conditions, include decreasing representatives such as ferrous sulfate, sodium sulfite, sodium bisulfite, sulfur dioxide, etc to minimize hexavalent chromium to trivalent chromium, and after that include salt hydroxide, calcium hydroxide, lime, and so on to change the pH value. Make it generate trivalent chromium hydroxide precipitate as well as different it from wastewater.
Ferrous Sulfate Heptahydrate Uses
In agriculture, it is made use of as fertilizer, herbicide as well as pesticide; in industry, it is used to make iron salt, ink, iron oxide red and also indigo, as mordant, tanning representative, water cleanser, wood preservative and anti-bacterial, etc.
Ferrous sulfate heptahydrate has a wide range of applications as well as can be made use of in industry, agriculture, medicine, food and other markets.
- In industry, it can be made use of for sewage as well as wastewater therapy. Ferrous sulfate heptahydrate has excellent decolorization capability and flocculation impact, as well as additionally has the functions of getting rid of heavy metal ions, degreasing, phosphorus elimination, as well as sanitation; Used as a reducing representative, it has an obvious effect on the co-precipitation of ferrite in electroplating wastewater; it can be utilized in iron red manufacturing facilities to produce resources such as magnetic iron oxide, iron oxide red and iron blue pigments.
- In farming, ferrous sulfate heptahydrate can be used as a pesticide as well as fertilizer to prevent as well as manage wheat smut, scab of apples and pears, rot of fruit trees, and also get rid of moss and lichen on tree trunks.
- In medication and also food, ferrous sulfate heptahydrate can be made use of as neighborhood astringent and also blood restorative, food iron fortifier, iron dietary supplement and also vegetables and fruit coloring agent to preserve the fresh color of pickled items.
- In speculative analysis, ferrous sulfate heptahydrate can be utilized as logical reagent.

The difference between ferrous sulfate and ferrous sulfate heptahydrate
Ferrous sulfate heptahydrate is the highest hydrate of ferrous sulfate, but the chemical properties of the two are not much different, and they can generally be used interchangeably.
From the chemical formula point of view, the difference between FeSO4 and FeSO4 7H2O is that it contains different crystal water, ferrous sulfate heptahydrate contains seven crystal water, and ferrous sulfate is a dehydrated crystal.
From the point of view of properties, ferrous sulfate will decompose into ferric oxide and release sulfur dioxide when heated, and its content is relatively high, generally more than 98%; while ferrous sulfate heptahydrate only passes through simple The impurity removal treatment is the reason for containing seven crystal waters. Its content is generally between 80-90%, its molecular weight is 278.05, and its melting point is 69°C.
From the application point of view, anhydrous ferrous sulfate contains crystal water, and its application is mostly for laboratory use; ferrous sulfate heptahydrate contains multiple crystal water, but it does not affect its chemical properties, so it is mostly used in wastewater treatment. It can be applied to cement to remove toxic chromate in cement, and because of its low cost, it is more widely used.
The difference in between ferrous sulfate heptahydrate as well as ferrous sulfate monohydrate
Different appearance: Ferrous sulfate monohydrate is also called feed quality ferrous sulfate. Its manufacturing procedure takes on wet dissolution to remove pollutants, as well as dehydration and also recrystallization are completely dry white or light white powder solids. Ferrous sulfate heptahydrate is gotten straight as a byproduct of the titanium dioxide manufacturing facility, as well as is a light green or eco-friendly granular strong. Ferrous sulfate heptahydrate has bigger crystal fragments than ferrous sulfate monohydrate
Different physical homes: Ferrous sulfate monohydrate will certainly break down into ferric oxide and also launch sulfur dioxide when warmed. Its web content is typically over 98%, its molecular weight is 169.9229, and also its melting point as well as boiling point are: 64 ° C as well as 330 ° C, respectively. Ferrous sulfate heptahydrate just goes through straightforward pollutant removal treatment in the titanium dioxide manufacturing facility and also has seven crystal waters. Its content is typically in between 80-90%, fairly unsteady, trickling sensation, molecular weight 278.05, melting point 69 ℃, and also ferrous sulfate heptahydrate is less complicated to redox response with air than ferrous monohydrate.
Various uses: Ferrous sulfate monohydrate is of iron feed grade, so it is commonly used as a feed additive. It has a great role in supplying nutritional iron to animals raised by iron, as well as protects against the occurrence of anemia diseases in pets. Boost the resistance of livestock to diseases during growth. It can also be used as a basic material for the production of iron oxide red and also other pigments. As well as slowly put on the plant food market. As a minimizing representative, ferrous sulfate heptahydrate is widely made use of in wastewater therapy for decolorization and flocculation. It can additionally be related to cement to eliminate hazardous chromate in cement, as well as it can be utilized as a blood tonic in medication and so on. As a result of its affordable, it is extra commonly used.
