Product Description

Product Description

chemical formula:FESO4.7H2O
Molecular weight: 278.01

Physical and chemical properties
   Appearance: It is usually a light blue or light green monoclinic crystal, with columnar or granular crystals, and the surface often appears rust colored due to oxidation.
   Odor: Odorless, salty and astringent in taste.
   Density: 1.897-1.91g/cm ³
   Melting point: 64 ºC
   Solubility: Easily soluble in water, the solubility in water increases with temperature. At 20 ºC, 26.5 grams of ferrous sulfate heptahydrate can be dissolved in every 100 milliliters of water; At 100 ºC, its solubility can increase to around 50 grams. Insoluble in organic solvents such as ethanol.
   Stability: It will gradually weather in dry air and turn into a white powder on the surface. It is easily oxidized in humid air, producing yellow brown basic iron sulfate. When heated to around 70 ºC, some crystal water will be lost and it will turn into white ferrous sulfate monohydrate; Continue heating to around 300 ºC, and the crystal water will be completely lost, turning into anhydrous ferrous sulfate; When the temperature is higher, anhydrous ferrous sulfate will decompose into iron oxide

Application

 

1. In the field of water treatment, it can be used as a flocculant to remove pollutants such as suspended solids, heavy metal ions, and phosphates from water. In the treatment of sewage and industrial wastewater, it can produce iron hydroxide colloids through hydrolysis, adsorb impurities in water, make the water clear, and achieve the goal of purifying water quality.

2. Agricultural field: It is an important iron fertilizer that can supplement iron elements for plants, prevent iron deficiency yellowing disease, improve plant photosynthesis efficiency and stress resistance, promote plant growth and development, especially suitable for crops such as flowers, fruit trees, and vegetables that prefer acidic soil.

3. Industrial production field: It is an important raw material for producing iron based pigments such as magnetic iron oxide and iron oxide red; Used as a paper sizing agent in the papermaking industry, it can improve the water resistance and strength of paper; Used as a tanning agent in the leather industry, it helps with the tanning and dyeing process of leather; In the construction industry, it can be used to prepare concrete admixtures and improve the performance of concrete.
