황산 철 C화학적 특성, 용도, 생산

개요

§184.1307(a) Ferric sulfate (iron(HI)sulfate, Fe2(S04)3), a yellow substance that may be prepared by oxidizing iron(II)sulfate or by treating ferric oxide or ferric hydroxide with sulfuric acid.

화학적 성질

Yellow crystals or grayish-white powder.(1) slightly soluble in water, (2) very soluble in water. Keep well closed and protected from light. Noncombustible.

화학적 성질

Ferric Sulfate is a grayish-white powder or yellow lumpy crystals.

물리적 성질

The anhydrous salt constitutes grayish-white rhombic crystals; hygroscopic; density 3.10 g/cm3; slightly soluble in cold water; decomposes in hot water. The nonahydrate is a yellow hexagonal crystalline substance; refractive index 1.54; density 2.10 g/cm3; hardness 2.5 Mohs; decomposes at 400°C; very soluble in water.

용도

Ferric Sulfate is a nutrient and dietary supplement that is a source of iron.

용도

In preparation of iron alums, other iron salts and pigments; as coagulant in water purification and sewage treatment; in etching aluminum; in pickling stainless steel and copper; as mordant in textile dyeing and calico printing; in soil conditioners; as polymerization catalyst.

정의

Ferrous sulfate,also known as ferrisulpas, green copperas, green vitriol, iron sulfate, and melanterite, is composed of blue green monoclinic crystals. It is soluble in water and is used as a mordant for dyeing wool in the textile industry. Ferrous sulfate is also used as a disinfectant and in the manufacture of ink.

제조 방법

Iron(III) sulfate may be prepared by oxidation of iron(II) sulfate by hydrogen peroxide, nitric acid or any other suitable oxidizing agent. The reaction is carried out in sulfuric acid. Balanced molecular equations for the reactions with hydrogen peroxide and nitric acid are as follows:
2FeSO4 + H2SO4 + H2O2 → Fe2(SO4)3 + 2H2O
6FeSO4 + 3H2SO4 + 2HNO3 → 3Fe2(SO4)3 + 2NO + 4H2O
Even in the absence of an oxidizing agent, concentrated sulfuric acid alone can1 convert iron(II) sulfate to iron(III) sulfate: 2FeSO4 + 2H2SO4→ Fe2(SO4)3 + SO2 + 2H2O It also may be prepared by treating iron(III) oxide with sulfuric acid:
Fe2O3 + 3H2SO4 → Fe2(SO4)3 + 3H2O
.

일반 설명

A yellow crystalline solid or a grayish-white powder. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Ferric sulfate is used for water purification, and as a soil conditioner.

공기와 물의 반응

Soluble in water. Hygroscopic in air. Forms acidic aqueous solutions.

반응 프로필

Ferric sulfate is acidic. Corrosive to copper, copper alloys, mild steel, and galvanized steel [USCG, 1999].

건강위험

Inhalation of dust irritates nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes and can irritate skin on prolonged contact.

농업용

Herbicide, Molluscicide, Agricultural product constituent: Ferric sulfate is used on forage alfalfa, almonds, nurseries and structural pest control. This material is also used in pigments, textile dyeing, water treatment, and metal pickling

상품명

GREENMASTER AUTUMN®; MAXICROP MOSS KILLER®; VITAX MICRO GRAN®; VITAX TURF TONIC®

Safety Profile

A poison by intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic fumes of SOx and Fe-. See also SULFATES and other ferric salts.

잠재적 노출

This material is used in pigments, textile dyeing, water treatment; and metal pickling.

운송 방법

UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz ardous material, Technical Name Required.

Purification Methods

Dissolve the sulfate in the minimum volume of dilute aqueousH2SO4 and allow it to evaporate at room temperature until yellowish-white crystals start to form. Do not concentrate by boiling off the H2O as basic salts will be formed. Various hydrates are formed; the common ones are the dodeca and nona hydrates which are violet in colour. The anhydrous salt is colourless and is very hygroscopic, but it dissolves in H2O slowly unless ferrous sulfate is added. [Gmelin’s, Iron (8th edn) pp 439-462 1932.]

비 호환성

Hydrolyzed slowly in aqueous solution. Incompatible with magnesium, aluminum. Corrosive to copper and its alloys, mild and galvanized steel. Light sensitive.

폐기물 처리

Treat with soda ash or dilute NaOH. Separate any precipitate and landfill. Flush solution to sewer.
