Blue green monoclinic crystals or particles, odorless. Weathered in dry air and oxidized to brown basic iron sulfate in moist air. At 56.6, it becomes four hydrate and becomes hydrate at 65. Soluble in water, almost insoluble in ethanol. When the water solution is cold, it slowly oxidized in the air and oxidized rapidly in the heat. Adding alkali or exposure can accelerate the oxidation of. Relative density (D15) 1.897. Irritant. Anhydrous ferrous sulfate is white powder, water of crystallization is light green crystal crystal, commonly known as "green", soluble in water, aqueous solution is light green. Ferrous sulfate can be used for chromatographic analysis reagents and spot analysis for the determination of platinum, selenium, nitrite and nitrate. Ferrous sulfate can also be used as a reducing agent to produce ferrite, water purification, polymerization catalyst, photo plate and so on.
Which can be used for preparing ferrous sulfate salts, iron oxide pigments, mordant, purifying agent, preservative and disinfectant;
Ferrous sulfate is used for flocculation and purification of water, and removal of phosphate from urban and industrial wastewater to prevent eutrophication of water bodies.
A large amount of ferrous sulfate is used as a reducing agent, mainly reducing chromate in cement.
Ferrous sulfate is used for the treatment of iron deficiency anemia; iron is also used in food, and long-term overuse may cause abdominal pain, nausea and other side effects.
It can also be used as a local astringent and a blood tonic, and can be used for chronic blood loss caused by uterine fibroids.
A, and other iron gall ink ink production requires the use of ferrous sulfate. Wood dyeing mordant also contains ferrous sulfate.
B, ferrous sulfate can be used to dye concrete to yellow rust color.
C, ferrous sulfate used for carpentry, maple dyed with silver color.
Regulating soil pH and promoting chlorophyll formation (also known as iron fertilizer) can prevent chlorosis caused by iron deficiency in flowers and trees. Hi is especially indispensable elements of acid and iron. Agriculture is also used as a pesticide, can control wheat smut, apple and pear scab scar and fruit trees rot; also can be used as fertilizer, can remove moss and lichen trunk.
Packaging and storage
In the summer shelf life of 30 days, the outer packaging are: 50 kg and 25 kg woven bags. Ferrous sulfate is widely used in the treatment of bleaching and dyeing, electroplating wastewater, water purification is an efficient flocculant, decolorization, especially used in bleaching wastewater is better; can be used as ferrous sulfate as raw material, ferrous sulfate is widely used in feed industry; is the main raw materials of electroplating wastewater with high efficiency flocculant polyferric sulfate the.
Operation notes: closed operation, partial air exhaust. Prevent dust from releasing into workshop air. Operators must undergo special training and strictly abide by the operating procedures. It is suggested that operators should wear self suction filter dust masks, wear chemical safety goggles, wear rubber acid and alkali clothing, and wear rubber gloves with acid and alkali resistance. Avoid dust. Avoid contact with oxidants and alkalis. Equipped with leakage emergency treatment equipment. Empty containers may have harmful effects.
Storage notes: stored in a cool, ventilated warehouse. Keep away from fire and heat. Prevent direct sunlight. Packing must be sealed, never damp. Should be separated from oxidants, alkalis, etc., should not be mixed storage. The storage area should be equipped with suitable materials for leakage.
