What is Anhydrous Ferrous Sulfate?

Anhydrous Ferrous Sulfate is a by-product produced during the production of a rare metal product. The appearance of the product is light green or light yellow-green crystalline solid, odorless, and has astringent taste with salty taste. Adding the agreed amount can adjust the pH value of alkaline water, organically combine with suspended solids in water, and accelerate precipitation. It is mainly used in water purification and industrial wastewater treatment, and has a bactericidal effect. The relative density is 1.899 (14.8°C), the melting point is 64°C, it loses 6 molecules of crystallization water at 90°C, and loses all crystallization water at 300°C. It is easy to weather in dry air, and gradually oxidizes in humid air to form yellow-brown basic iron sulfate. The anhydrous substance is a white powder with a relative density of 3.4, and it turns blue-green when reacted with water. pH (1+10 solution) 3.7.

Uses of Anhydrous Ferrous Sulfate

1. Anhydrous Ferrous Sulfate is mainly utilized as a flocculant: the flocculation result is excellent, it has a good decolorization capability, and it additionally has the features of getting rid of heavy metal ions, oil removal, phosphorus removal, and sanitation, particularly for the decolorization of printing as well as coloring wastewater and also the elimination of COD as well as electroplating wastewater The ferrite co-precipitation and various other results are obvious, and its rate is cheap, it is a just item for printing and dyeing, electroplating and also other wastewater therapy.

2. Anhydrous Ferrous Sulfate can additionally be used as preservative, pigment, raw material for digital sector, hydrogen sulfide antiperspirant, soil conditioner, commercial driver, and so on 3. Clinical field: mostly reflected in iron and also blood supplements, therapy of iron deficiency anemia; likewise utilized as regional astringent as well as blood tonic. To treat anemia, possible side effects include queasiness and top stomach discomfort.

Anhydrous Ferrous Sulfate is oxidized to Fe3+ by ceruloplasmin in blood, then combined with transferrin in plasma, and carried to different cells in the body. Goes into the cell in the form of pinocytosis with the transferrin receptor. Iron likewise joins several biochemical processes in the body, consisting of electron transportation in mitochondria, catecholamine metabolic rate, as well as DNA synthesis. In addition, it incorporates with protoporphyrin as well as globin on the mitochondria to form hemoglobin.

4. Industrial field: industrially used to manufacture salt, ink, iron oxide red and indigo, etc, as well as made use of as mordant, tanning representative, detergent and also anti-bacterial and also wood preservative, and so on. Its pharmaceutical series include polyacrylamide (cation, anion), polyaluminum chloride, polyaluminum ferric chloride, standard aluminum chloride, ferric chloride, phosphoric acid, trisodium phosphate, potassium dihydrogen phosphate, and so on. In farming, it is used as chemical fertilizer, pesticide and herbicide to deal with wheat smut and more. In cosmetics it is made use of as an astringent and deodorant and as a hair dye. In water treatment, it is mainly made use of as a coagulant for turbid water bodies. Since it is acidic after hydrolysis, it is commonly used in mix with lime in practice. The impressive attribute is lowering, and also it is usually utilized in water treatment of wastewater with high-valent heavy metal ions.

Anhydrous Ferrous Sulfate Oral Precautions

1. People with ulcer condition, ulcerative colitis and also hemolytic anemia must not use it.
2. Stay clear of drinking tea as well as milk throughout the medicine.
3. Taking it after dishes can lower stomach inflammation.
4. The feces might transform black after taking it.
5. When made use of together with antacids, cholestyramine, pancreatin, penicillamine and also tetracycline, the effect of this product can be damaged.
6. Medications that can enhance the result of this product consist of vitamin C and also thin down hydrochloric acid.
7. Drugs that ought to not be made use of in mix are: tannic acid, tannic acid protein and dimercaptopropanol.
8. It is contraindicated in people with hemochromatosis, hemosiderosis, iron allergy and also drastically damaged liver as well as kidney feature.
9. The following products need to be kept track of during treatment: hemoglobin, reticulocyte count, serum ferritin, and serum iron.
10. Taking a huge amount by mouth can trigger acute poisoning, gastrointestinal bleeding, death, and also shock in extreme instances, and also need to be treated immediately.

Anhydrous Ferrous Sulfate Water Treatment Field

liquid-liquid precipitation method

Utilize ferrous ammonium sulfate solution and sodium sulfide solution to react to form ferrous sulfide precipitate, and then obtain higher purity Anhydrous Ferrous Sulfate through precipitation separation, centrifugation, washing and drying. The reaction equation is as follows:

Figure 1 Anhydrous Ferrous Sulfate reaction equation


Completely dissolve 2g of sodium sulfide in 10ml of high-purity water to obtain a sodium sulfide solution; weigh 3g of ferrous ammonium sulfate and add water to dissolve it. Slowly add the prepared sodium sulfide solution into the ferrous ammonium sulfate solution, and keep stirring to obtain a black solid suspension. After separation and drying, ferrous sulfide samples can be obtained.

gas-liquid precipitation method

Utilize commercially available ore ferrous sulfide and sulfuric acid to react in the Kipp generator to produce hydrogen sulfide gas, and obtain a solid-liquid mixture containing Anhydrous Ferrous Sulfate particles by hydrogen sulfide gas to ferrous ammonium sulfate solution for a long time. Ferrous sulfide with higher purity can be obtained through precipitation separation, centrifugation, washing and drying. Since the gas hydrogen sulfide produced during the experiment is a toxic gas, all experiments were carried out in a fume hood.


The gas reaction bottle is equipped with ferrous ammonium sulfate solution, and the tail gas absorption bottle is a dilute sodium hydroxide solution for tail gas treatment. After checking the airtightness of the experimental device, add 150ml~200ml of 50% sulfuric acid solution to the Kipp generator equipped with block Anhydrous Ferrous Sulfate reagent, react for 48 hours, and put the The solid-liquid mixture was taken out to separate and dry.

gas-solid reaction method

Utilize commercially available ore ferrous sulfide and sulfuric acid to react in the Kipp generator to produce hydrogen sulfide gas, pass the hydrogen sulfide gas into the glass tube containing the ferric oxide solid, and grow the ferric oxide solid through the hydrogen sulfide gas Corrosion of time yields ferrous sulfide solids. Then extract and remove sulfur with an organic solvent, and obtain higher-purity ferrous sulfide through precipitation separation, centrifugation, washing and drying.


Put the ore Anhydrous Ferrous Sulfate in the Kipp generator, and the reaction tube is filled with ferric oxide solid but not too dense (to facilitate the circulation of hydrogen sulfide gas and maximize the use of hydrogen sulfide gas). After checking the airtightness of the experimental device, add 150ml~200ml of 50% sulfuric acid solution to the Kip generator, react for 48 hours, take out the solid in the No. 2 reaction tube for extraction, and then separate and dry to obtain sulfuric acid Ferrous samples. Since the gas hydrogen sulfide produced during the experiment is a harmful gas, all experiments were carried out in a fume hood.
