• 使用

  Vanadium is a metallic element that occurs in six oxidation states and numerous inorganic compounds. Some of the more important compounds are vanadium pentoxide (V2O5), sodium metavanadate (NaVO3), sodium orthovanadate (Na3VO4), vanadyl sulfate (VOSO4), and ammonium vanadate (NH4VO3). Vanadium is used primarily as an alloying agent in steels and non-ferrous metals (ATSDR, 1990). Vanadium compounds are also used as catalysts and in chemical, ceramic or specialty applications.

• 定義

  ChEBI: Sodium metavanadate is an inorganic sodium salt having metavanadate as the counterion. It contains a metavanadate.

• 製造方法

  sodium metavanadate synthesis: Dissolve vanadium pentoxide in sodium hydroxide solution, crystallized by concentration, that is, the finished product of sodium metavanadate.
  V2O5+2NaOH→2NaVO3+H2O

• 一般的な説明

  Colorless to yellow crystals or cream colored solid. Melting point 630°C.

• 空気と水の反応

  Soluble in water.

• 反応プロフィール

  Sodium metavanadate is a moderately strong oxidizing agent [Cotton and Wilkinson].

• 危険性

  Toxic by ingestion.

• 健康ハザード

  Vanadium pentoxide and sodium metavanadate have a toxicity rating of 5, equivalent to a probable lethal oral dose in humans of 5-50 mg/kg (Gosselin et al., 1984). The elemental metallic form is considered to be non-toxic.
  Stokinger et al. (1953) reported that a 10% solution of sodium metavanadate is a primary irritant to human skin. Saturated solutions of ammonium metavanadate (0.5%) and vanadium pentoxide (0.8% solution) did not irritate the skin. Sjoberg (1951) reported that several workers occupationally exposed to vanadium developed what appeared to be a contact dermatitis and that in one case, skin patch tests produced eczematous lesions indicative of an allergic reaction.
  COMMENTS: The NOAEL is derived from a study in which rats were given 0, 5, 10 and 50 ppm sodium metavanadate, in drinking water for 3 months. Impaired kidney function was seen at 50 ppm, and 10 ppm was considered a NOAEL. The Uncertainty Factor of 100 is the product of a 10-fold uncertainty in extrapolating from laboratory animals to humans and a 10-fold uncertainty to protect sensitive individuals.

• 火災危険

  Flash point data of Sodium metavanadate are not available. Sodium metavanadate is probably nonflammable.

• 安全性プロファイル

  Poison by ingestion, intraperitoneal, subcutaneous, and intravenous routes. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of Na2O and VOx. See also VANADIUM COMPOUNDS.
