메타-비산 나트륨 화학적 특성, 용도, 생산

• 화학적 성질

  White crystalline, odorless solids.

• Safety Profile

  Confirmed human carcinogen. A poison. Mutation data reported. See also ARSENIC COMPOUNDS. When heated to decomposition it emits toxic fumes of arsenic.

• 잠재적 노출

  (dibasic): Sodium arsenate is used in dyeing and printing; making other arsenates; as a germicide; in dyeing with turkey-red oil.

• 운송 방법

  UN1685 Sodium arsenate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

• 비 호환성

  Sodium arsenate reacts with moisture, steam, and water; forming flammable and toxic arsenic hydride. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Sodium arsenate is a weak oxidizing agent that may react with reducing agents, including hydrides. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, chemically active metals. Arsine, a very deadly gas, can be released in the presence of acid, acid mists; or hydrogen gas. Attacks many metals (such as aluminum, iron, and zinc) in presence of moisture producing arsenic and arsine fumes

• 폐기물 처리

  Dissolve in minimum quantity of concentrated, reagent hydrochloric acid. Filter if necessary. Dilute with water until white precipitate forms. Add just enough 6M HCl to redissolve. Saturate with hydrogen sulfide. Filter, wash the precipitate; dry, package, and ship to the supplier.
