| Gesundheitsgefahren | SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes, respiratory tract and gastrointestinal tract. Ingestion can cause severe gastroenteric distress (vomiting, pain, localized corrosion, and hemorrhages), prostration, anuria, hematuria, anemia, increased number of white blood cells, icterus, coma, respiratory difficulty and circulatory failure. It can also cause nausea, metallic taste, sweating, headache, burning sensation in the esophagus and stomach, abdominal pain, hemorrhagic gastritis, weak pulse, melena, conjunctivitis, corneal ulceration, hypotension and turbidity. Other symptoms may include watery and bloody stools, burning in the mouth and throat, liver damage with jaundice, hemolysis, tenesmus, retching, collapse and convulsions. Uremia, shock and renal failure have been reported. Skin contact can cause smarting and first degree burns on short exposure. Prolonged exposure can result in second degree burns. Persons with preexisting Wilson's disease may be more susceptible to these effects. |
Anwendungen & Verwendung
Beschreibung
Copper(II) sulfate pentahydrate is known as blue vitriol. It is an odorless blue crystal that readily dissolves in water. It is also soluble in methanol, glycerol and slightly soluble in ethanol. The highly toxic, non-combustible has a nauseating metallic taste and turns white when dehydrated. Structurally, in the pentahydrate molecule, each copper(II) ions is surrounded by four water molecules in the corners and the fifth water molecule is attached by hydrogen bonding. Copper (II) sulfate has many applications including preparation of Bordeaux mixture, a fungicide preparation. Electroplating, timber preservation and textile industry use copper (II) sulfate.
Verwenden
Copper (II) sulfate pentahydrate salt may be used for the fabrication of copper nanoparticles by chemical reduction. The pentahydrate salt of copper may be used as a catalyst for the conversion of aromatic aldehydes to primary amides via aldoximes. Reduced graphene oxide-supported copper nanoparticles (rGO/Cu NPs) may be prepared by copper (II) sulfate pentahydrate and graphitic precursors. An aqueous electrolytic bath containing CuSO4.5H2O as one of the constituents was used for the preparation of Cu2ZnSnS4 (CZTS) thin film solar cell. Ferric chloride hexahydrate (FeCl3.6H2O) and copper(II) sulfate pentahydrate (CuSO4.5H2O) may be used to fabricate Fe-Cu binary oxide sorbents for arsenic removal applications.
