Role and purpose
The system for iron, iron oxide pigments, mordant, water purifying agent, preservatives, disinfectants, etc.;
Medicine for anti-anemia drugs, blood agents and local convergence agent for chronic blood loss caused by uterine fibroids;
Analytical reagents and manufacturing ferrite materials;
Flocculation of ferrous sulfate can be used for water purification, and removal of phosphate from municipal and industrial wastewater to prevent eutrophication of water bodies;
A lot of ferrous sulfate is used as a reductant, mainly the reduction of chromate in cement;
As a feed additive iron supplements;
Can be used as agricultural pesticides, can prevent wheat smut, apples and pears scar scab, fruit rot; edible used as nutritional supplements, such as iron supplements, fruit and vegetable coloring agent.
Also be used as fertilizer, iron supplements as plants, control plants should occur physiological deficiency diseases, the plant leaf chlorosis. Can remove moss and lichens trunk. Manufacturing of magnetic iron oxide, iron oxide red and iron blue inorganic pigments, iron catalysts and materials poly ferric sulfate.
Oh used range from 5.5 to 9.6, the temperature has little effect on its flocculation. Applicable to large concentrations, strong alkaline water. Flocculation stability, rate of formation of floc fast, good flocculation. But more corrosive. Not only do flocculants, and widely used in industrial and agricultural production. It is a micronutrient fertilizer, has accelerated rice, sugar beet turn green, and in alkaline soil, and promote farm manure composting to improve the growing conditions of plants and so on. [1]
In addition, other reagents used for chromatographic analysis.
1, water treatment
Flocculation of ferrous sulfate for water purification, and removal of phosphate from municipal and industrial wastewater to prevent eutrophication of water bodies.
2, reducing
A lot of ferrous sulfate is used as a reductant, mainly the reduction of chromate in cement.
3, medicinal
Ferrous sulfate for the treatment of iron deficiency anemia; are also used in food with iron, long-term excessive use may cause abdominal pain, nausea and other side effects.
4, a coloring agent
a, iron gall ink and other inks used in the production of ferrous sulfate needs. Mordant dye wood also contain ferrous sulphate.
b, ferrous sulfate can be used to concrete stained yellow rust.
c, wood stained with ferrous sulfate to make maple silver color.
5 Agriculture
Adjust the soil pH, prompting the formation of chlorophyll (also known as iron fertilizer), can prevent iron deficiency caused by flowers and yellowing disease. Hi acidic cycads flowers, especially indispensable element.
Can be used as agricultural pesticides, can prevent wheat smut, apples and pears scar scab, fruit rot; also be used as fertilizer, can remove moss and lichens trunk. Manufacturing of magnetic iron oxide, iron oxide red and iron blue inorganic pigments, iron catalysts and materials poly ferric sulfate. Used as a topical astringent agents and blood tonic medicine. In addition, other reagents used for chromatographic analysis. Edible used as nutritional supplements, such as iron supplements, fruit and vegetable coloring agent. Feed-grade ferrous sulfate in feed processing as iron supplements
Usage:
①, 10 克 watered 4 to 5 pounds, foliar spray.
②, the normal growing season, 1 to 2 times per month.
③, disease prevention period, 10 to 15 days, for 2 to 3 times.
Dosage: 10 grams watered 7-9 pounds, watering basin, about 20 days.
Disease prevention and principles: Indications yellow disease, mainly in young leaves, before the beginning of mesophyll yellowing leaves on both sides after the central focus or brown spots appear tip; long time, leaves fall off.
6, other
a, horticulture using ferrous sulphate to kill moss.
b, after the 19th century, ferrous sulfate was used as a photographic developer Corot tincture law.
c, of brass contact with ferrous sulfate turbine condenser, a corrosion protective layer is generated on the inner surface of the tube.
