Ferrous sulfate, iron (II) is an inorganic compound of formula FeSO4, the most commonly used is its blue-green heptahydrate. Anhydrous ferrous sulfate is a white powder, containing water of crystallization is light green crystals, crystal commonly known as "copperas," soluble in water as a pale green solution. Part I: Chemical name Chemical Chinese name: English name of the chemical ferrous sulfate: ferrous sulfate Chinese name 2: green vitriol Name 2: green vitriol Technical Manual Code: 2536 CAS No:. 7782-63-0 Formula: FeSO4 Ferrous sulfate crystals Formula: FeSO4 7H 2O (also called green vitriol) Weight:? 278.05 Product Standard: GB10531-89 Part II: Composition / information on ingredients CAS No harmful ferrous sulfate 7782-63-0 [preparation]. (1) sulfuric acid method: scrap iron reacts with sulfuric acid, precipitated crystals that get dehydrated ferrous sulfate, the reaction is as follows: Fe + H2S04 a FeS04 ten H2 ↑ (2) production of titanium dioxide by-product: the ilmenite * Preparation of titanium production byproducts obtained. Technical index Item Index (industrial water treatment) Premium grade First grade Qualified ferrous sulphate FeS04? 7H2O /% ≥ 97.0 94.0 90.0 Titanium dioxide TiO2 /% ≤ 0.5 0.5 0.75 Water insoluble /% ≥ 0.5 0.5 0.75 Third Part I: HAZARDS risk categories: pathways: health hazards: respiratory tract irritation, coughing and shortness of breath caused by inhalation. The eyes, skin and mucous membrane irritant. Swallowed cause weakness, abdominal pain, nausea, bloody diarrhea, lung and liver damage, shock, coma, severe cases can be fatal. Environmental hazards: hazard to the environment, can cause pollution of water bodies. Explosion hazard: The product is flammable, irritating. Part IV: First aid measures Skin contact: Remove contaminated clothing, rinse with plenty of water. Eye contact: Did eyelid, mobile water or saline. Doctor. Inhalation: rapidly from the scene to fresh air. Keep the airway patency. If breathing is difficult, give oxygen. If not breathing, give artificial respiration immediately. Doctor. Ingestion: water were found to blues or egg white. Doctor as soon as possible. Part V: Fire-fighting measures: a reduction. Decomposition by high fever and emit toxic gases. Hazardous combustion products: sulfur oxides. Fire fighting methods: firefighters must wear fire protective body suits, fire in the wind. Possible to move containers from the scene empty Department during the fire. Then select the appropriate extinguishing agent fire causes. Part VI: Leak Emergency treatment: isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing dust masks, wearing overalls general operations. Do not direct contact with leakage. A small leak: to avoid dust, carefully scan, collected in a dry, clean, covered containers. Large Leak: recycling or collection shipped to the waste disposal sites. Part VII: HANDLING AND STORAGE Handling Precautions: closed operation, local exhaust ventilation. Prevent dust released into the air workshop. The operator must go through specialized training, strict adherence to rules. Proposed operators wear self-absorption filter respirators, wearing chemical protective safety glasses, wear rubber acid suit, wear rubber gloves acid. Avoid generating dust. Avoid contact with oxidizing agents, alkalis. Equipped with spill response equipment. Empty containers may be harmful residues. Storage: Store in a cool, ventilated warehouse. Keep away from fire and heat. Prevent direct sunlight. Packaging must be sealed, not damp. Should be stored separately with oxidants, bases, etc., avoid mixing reservoir. Storage areas should be equipped with suitable material spill. Easily oxidized in air, must now use the existing experiments.
