概要
Iron(2+) sulfate heptahydrate is a hydrate that is the heptahydrate form of iron(2+) sulfate. It is used as a source of iron in the treatment of iron-deficiency anaemia (generally in liquid-dosage treatments; for solid-dosage treatments, the monohydrate is normally used). It has a role as a nutraceutical, a reducing agent and an anti-anaemic agent. It is an iron molecular entity and a hydrate. It contains an iron(2+) sulfate (anhydrous).

説明§184.1315(a) Ferrous sulfate heptahydrate (iron (II) sulfate heptahydrate, FeS04-7H2O) is prepared by the action of sulfuric acid on iron. It occurs as pale, blueish-green crystals or granules. Progressive heating of ferrous sulfate heptahydrate produces ferrous sulfate (dried). Ferrous sulfate (dried) consists primarily of ferrous sulfate monohydrate (CAS No. 17375-41-6) with varying amounts of ferrous sulfate tetrahydrate (CAS No. 20908-72-9) and occurs as a grayish-white to buff-colored powder.
使用Used in quantitative analysis of nitrates .
一般的な説明A greenish or yellow-brown crystalline solid. Density 15.0 lb /gal. Melts at 64°C and loses the seven waters of hydration at 90°C. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Used for water or sewage treatment, as a fertilizer ingredient.
調製方法
純化方法Crystallise the sulfate from 0.4M H2SO4, or precipitate it from an aqueous solution with EtOH. It is efflorescent in dry air, and is converted to the tetrahydrate at 57o, then to the monohydrate at 65o (or by heating the heptahydrate in a vacuum at 140o). It forms a brown-black complex, FeSO4.NO, with nitric oxide and is used in a qualitative test for nitrates (“brown ring” test).
