strontium nitrate solution - Preparation Method
Open Data Verified Data
- Celite method: add 200 mesh Celite ore powder into the calcium remover, and then add hydrochloric acid and appropriate amount of water, so that the pH value of the solution is 1~2, after heating to near boiling for 2H with stirring, the calcium carbonate in the ore is converted into calcium chloride and transferred into solution. Put the material into a calcium-removing scrubber, decant the clear liquid after settling, repeatedly wash the slurry with hot water until the solution is neutral, send the slurry to the converter, add the saturated solution of soda ash, and heat it with steam, the metathesis reaction was carried out for 2H with stirring until the pH of the reaction solution was 10. After sedimentation, the clear liquid was decanted, and the precipitate was washed repeatedly with hot water until the pH of the solution was 7-8 to remove sodium sulfate and sodium carbonate. The slurry was fed to the reactor, and 98% nitric acid was slowly added with stirring until the pH of the reaction solution was 4 to 5. After pressure filtration, the filtrate is concentrated by evaporation to precipitate crystals, centrifuged while hot, and dried at 100-150 ° C. To obtain a finished strontium nitrate product.
- strontium carbonate method: strontium carbonate is added into the reactor, and 98% nitric acid is slowly added under stirring for reaction until the pH value of the reaction solution is 4-5. After pressure filtration, the filtrate is sent to an evaporator to be evaporated and concentrated to precipitate crystals, centrifuged while hot, and dried at 100 N150 ° C. To obtain a strontium nitrate finished product.

Open Data Verified Data
- rats were intraperitoneally injected with LD0:540mg/kg. It has a stimulating effect on the eyes, skin and mucous membranes. Staff should be protected. If the skin and eyes are touched, they should be immediately rinsed with plenty of water.
- packed in plastic woven bags lined with polyethylene plastic bags, each with a net weight of 25kg; Packed in iron barrels lined with plastic bags, each with a net weight of 50kg. It should be obvious on the package. Oxidant "sign. It belongs to class I inorganic oxidant, with Hazard code number: GB 51 class 51059. UNN0.1507; IMDG CODE page 5187, Class 3. Should be stored in a cool, ventilated, dry warehouse. Storage temperature should not exceed 30 ℃. Should be moisture-proof. It is not allowed to be stored and mixed with organic matter and flammable materials, and should be protected from rain and sun exposure during transportation. Handling should be careful to prevent packaging rupture. Fire, water, sand, all kinds of fire extinguishing, but to avoid the flow of aqueous solution to the flammable goods. Toxicity and protection: inhalation of strontium nitrate dust can cause moderate diffuse changes in the lungs. Contact with the skin causes sensitization and the occurrence of eczematous dermatitis. The maximum allowable concentration is 1mg/m3. Production workers should wear work clothes, masks, latex gloves and other labor protection articles to prevent inhalation and exposure to strontium nitrate dust to protect respiratory organs and skin.
