All federal, state, and local environmental regulations must be observed. Use a licensed professional waste disposal service to dispose of this material. May react as either oxidizing agents or reducing agents 폐기물 처리 비 호환성Īqueous solution reacts with bases, generating some heat. 1) Biological limit values ACGIH Biological Exposure Indices Components Value Determinant Specimen Sampling Time Cobalt Sulfate, 15 g/l Cobalt Urine Monohydrate (CAS 1) - For sampling details, please see the source document. The pale reddish or lavender-coloured anhydrous salt is obtained by heating the hydrate above 250o, boiling with conc H2SO4 or heating with (NH4)2SO4). Between 44o and 70o the monoclinic hexahydrate CoSO4.6H2O m 41.5o is formed, and above 70o the monohydrate CoSO4.H2O m 71o is obtained. The heptahydrate crystallises below 44o and is efflorescent with m 97o. Purification MethodsĬrystallise it three times from conductivity water (1.3mL/g) between 100o and 0o depending on which hydrate is required. UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1 Labels: 6.1-Poisonous materials, Technical Name Required. CarcinogenicityĬobalt sulfate is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals. Many be used to catalyze organic reactions. Safety ProfileĪnd intraperitoneal routes. Special Hazards of Combustion Products: Toxic cobalt oxide fumes may form in fire. Contact with eyes or skin causes irritation. Inhalation causes shortness of breath and coughing permanent disability may occur. Many of these compounds catalyze organic reactions. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. 공기와 물의 반응Īcidic salts, such as Cobalt sulfate, are generally soluble in water. 용도Ĭeramics, pigments, glazes, in plating baths forĬobalt, additive to soils, catalyst, paint and ink drier, Red powder or rose pink crystalline solid. The sulphate is believed like the alums to contain the 3+ ion. The hydrated sulphate also has a small positive magnetic susceptibility. and the ammonium alum has a moment of 2.1 B.M. The potassium alum is diamagnetic, the rubidium salt has a magnetic moment less than 1 B.M. Cobalt(III) alums MCo(SO4)2.12H2O (M = K, Rb, Cs or NH4) can be isolated as blue crystals from the mixed cooler solutions of the two sulphates in dilute sulphuric acid. It is stable in the dry state, but is decomposed by water with evolution of oxygen it is fairly stable in solution in dilute sulphuric acid. OSHA Process Safety Management (PSM) Standard List No regulatory information available.The blue, crystalline hydrate Co2(SO4)3.18H2O is prepared by the oxidation of cobalt(II) sulphate in 8N sulphuric acid either electrolytically or chemically with ozone or fluorine.
