황산철(Ⅱ) C화학적 특성, 용도, 생산

용도

1.제지 산업 그것은 중립과 알칼리성 PH에 종이의 정립에서 도와, 따라서 서류상 질을 (반점과 구멍을 감소시키고 장 대형과 힘 개량하기) 개량하고 효율성을 치수를 재.
2.물 유출하는 치료 시스템 그것은 식용수 및 폐수 처리의 정화를 위해 강수와 응집에 의하여 불순의 침전해서 사용했습니다.
3.섬유 산업 그것은 면 직물을 위한 나프톨에 근거한 염료에 있는 색깔 담합을 위해 사용됩니다.

화학적 성질

Greenish or yellow-brown crystals or granules; odorless. Soluble in water with saline taste; insoluble in alcohol. hygroscopic.

화학적 성질

Ferrous sulfate is a greenish or yellowish solid in fine or lumpy crystals.

용도

Ferrous Sulfate is a nutrient and dietary supplement that is a source of iron. it is a white to grayish odorless powder. ferrous sulfate hep- tahydrate contains approximately 20% iron, while ferrous sulfate dried contains approximately 32% iron. it dissolves slowly in water and has high bioavailability. it can cause discoloration and rancidity. it is used for fortification of baking mixes. in the encapsulated form it does not react with lipids in cereal flours. it is used in infant foods, cereals, and pasta products.

용도

Iron Supplement

용도

Ferrous sulfate (FeSO4) is also known as iron sulfate or iron vitriol. It is used in the production of various chemicals, such as sulfur dioxide and sulfuric acid.

정의

A rusty-brown solid prepared by the action of heat on iron(III) hydroxide or iron(II) sulfate. It occurs in nature as the mineral hematite. Industrially it is obtained by roasting iron pyrites. Iron(III) oxide dissolves in dilute acids to produce solutions of iron(III) salts. It is stable at red heat, decomposes around 1300°C to give triiron tetroxide, and can be reduced to iron by hydrogen at 1000°C. Iron(III) oxide is not ionic in character but has a structure similar to that of aluminum(III) oxide.

정의

Copperas: an off-whitesolid, FeSO4.H2O; monoclinic; r.d.2.970. There is also a heptahydrate,FeSO4.7H2O; blue-green monoclinic;r.d. 1.898; m.p. 64°C. The heptahydrateis the best known iron(II) saltand is sometimes called green vitriolor copperas. It is obtained by the actionof dilute sulphuric acid on ironin a reducing atmosphere. The anhydrouscompound is very hygroscopic.It decomposes at red heat to giveiron(III) oxide, sulphur trioxide, andsulphur dioxide. A solution of iron(II)sulphate is gradually oxidized on exposureto air, a basic iron(III) sulphatebeing deposited.

위험도

Ingestion causes intestinal disorders.

농업용

Copperas, also called green vitriol, is ferrous sulphate heptahydrate. It is an iron salt fertilizer, which is most effective in overcoming iron deficiency.

농업용

Ferrous sulphate heptahydrate (FeSO4.7H2O), also called green vitriol or copperas, is a blue-green water-soluble crystal and is the best known ferrous salt. It is obtained by the action of dilute sulphuric acid on iron in a reducing atmosphere. The anhydrous compound is very hygroscopic. It gets oxidized gradually in an aqueous solution. On heating, the solid decomposes to give red ferric oxide, sulphur trioxide (SO3) and sulphur dioxide (SO2).

Safety Profile

A human poison by ingestion. Moderately toxic to humans by an unspecified route. An experimental poison by ingestion, intraduodenal, intraperitoneal, intravenous, and subcutaneous routes. Human systemic effects by ingestion: aggression, somnolence, brain recorlng changes, diarrhea, nausea or vomiting, bleedmg from the stomach, coma. Questionable carcinogen with experimental tumorigenic data. Experimental teratogenic and reproductive effects. Mutation data reported. Potentially explosive reaction with methyl isocyanoacetate at 25'. May igmte on contact with arsenic trioxide + sodium nitrate. When heated to decomposition it emits toxic fumes of SOx. See also IRON COMPOUNDS.

잠재적 노출

It is used as a fertilizer, food or feed additive; and in herbicides; process engraving; dyeing, and water treatment. A byproduct of various chemical and metal treating operations.

Veterinary Drugs and Treatments

While iron is a necessary trace element in all hemoglobin-utilizing animals, the use of therapeutic dosages of ferrous sulfate (or other oral iron) preparations in veterinary medicine is limited primarily to the treatment of iron-deficiency anemias in dogs (usually due to chronic blood loss), and as adjunctive therapy in cats when receiving epoetin (erythropoietin) therapy. Injectable iron products are usually used in the treatment of iron deficiency anemias associated with newborn animals.

비 호환성

Aqueous solution is acidic. Contact with alkalies form iron. Keep away from alkalies, soluble carbo nates; gold and silver salts; lead acetate; lime water, potassium iodide; potassium and sodium tartrate; sodium borate; tannin.
