• 定義

  本品は、硫酸(*)の第二鉄塩であり、次の化学式で表される。
  参照表示名称：硫酸

• 解説

  硫酸鉄(Ⅲ)　無水和物Fe2(SO4)3、式量399.9（硫酸第二鉄ともいう）のほか三、六、七、7.5、九、十、12水和物がある。このうちあとの5種は天然にも存在する。硫酸鉄(Ⅱ)の水溶液を酸化し、蒸発濃縮すると、水和物の結晶が得られるが、結晶化の条件によって結晶水の数が異なってくる。水和物を注意して加熱、脱水すると無水和物が得られる。無水和物は白色ないし淡黄色の粉末。潮解性。加熱により約480℃で分解し酸化鉄となる。水にわずかに溶けるが、加水分解の結果溶液は褐色を呈し、温めるとただちに塩基性硫酸鉄(Ⅲ)または酸化水酸化鉄(Ⅲ)の赤褐色沈殿を生ずる。鉄ミョウバンおよびプルシアンブルーの製造に用いられるほか、媒染剤、医薬としての用途もある。

  外用止血薬

• 説明

  §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.

• 化学的特性

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

• 物理的性質

  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.

• 使用

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

• 製造方法

  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
  .

• 定義

  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.

• 一般的な説明

  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.

• 空気と水の反応

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

• 反応プロフィール

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

• 健康ハザード

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

• 农业用途

  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

• 製品名

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

• 安全性プロファイル

  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.

• 職業ばく露

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

• 輸送方法

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

• 純化方法

  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.]

• 不和合性

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

• 廃棄物の処理

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