定義
ChEBI: A hydrate composed of cadmium sulfate and water in a 3:8 ratio.
安全性プロファイル
Confirmed human
carcinogen with experimental tumorigenic
and neoplastigenic data. Experimental
teratogenic and reproductive effects.
Mutation data reported. When heated to
decomposition it emits very toxic fumes of
Cd and SO,. See also CADMIUM
SULFATE, CADMIUM COMPOUNDS,
and SULFATES.
職業ばく露
It is used in pigments, electroplating;
as a fungicide; and in synthetic and analytical chemistry.
Also used in fluorescent screens; as an electrolyte.
Incompatibilities: Acts as a weak inorganic acid; neutralizes bases. Incompatible with oxidizers (chlorates, nitrates,
peroxides, permanganates, perchlorates, chlorine, bromine,
fluorine, etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, epoxides, sulfur, selenium, tellurium, zinc

6.1; Labels: 6.1-Poisonous materials, Technical Name
Required.
純化方法
The sulfate crystallises from distilled water as a hydrate by partial evaporation in a desiccator. It gives the monohydrate on heating at 80o. It is insoluble in EtOH, Me2CO or EtOAc. It forms a white precipitate of Cd(OH)2 with aqueous NH3 which dissolves in excess of NH3 to form soluble [Cd(NH3)4]SO4. [Gmelin’s Cadmium (8th edn) 33 p 121 1925, Suppl pp 609-610 1959.]
