cadmiumcarbonate(cdco3) - Safety
Open Data Verified Data
- double plastic bags, each bag with a net weight of 20kg; Or packed with hemp bags and wooden boxes lined with plastic bags, each bag (box) with a net weight of sokg, and the package should have a clear "toxic product" Mark; it should be stored in a cool, ventilated and dry warehouse, and should be protected from damage when placing the container, to avoid moisture, and not mixed with food; During transportation, it should be protected from sunlight exposure. It is an inorganic drug. When disposing of the escaping material, wear a gas mask and gloves, mix it with wet sand, sweep it up and pour it into the waste bin, the diluted wash water was placed into the wastewater system.
- toxicity and protection: highly toxic. Less soluble cadmium compounds first act on the respiratory organs and gastrointestinal tract, absorption of the central nervous system and peripheral nervous system, internal organs, mainly heart, kidney, liver, damage of skeletal muscle and bone tissue. Acute poisoning of cadmium oxide dust, visible upper respiratory tract and respiratory tract deep mucosa irritation symptoms, such as sweet taste in the mouth, forehead pain, dizziness, weakness, Nausea, upper abdominal pain, chronic poisoning symptoms are decreased sense of smell, Head Pain, weight loss. The maximum allowable concentration of cadmium oxide dust is 0. 1mg/m3, and the daily average concentration is 0. 03mg/m3. In case of poisoning, the patient should be quickly moved to a place with fresh air, be quiet and warm. If there is respiratory irritation, the patient should inhale a warm 2% sodium bicarbonate solution, and wear a gas mask and protective glasses when working, wear seamless work clothes or pants, rubber gloves and aprons, and rinse your mouth during and after work.

| solubility in water (g/100ml) | dissolved grams per 100ml of water: 3.932 × 10-5/20 ℃ |
| toxicity | highly toxic. Cadmium compounds with lower solubility first act on respiratory organs and gastrointestinal tract, and their absorption is manifested as damage to the central nervous system and peripheral nervous system, internal organs, mainly heart, kidney, liver, skeletal muscle and bone tissue. Acute poisoning of cadmium oxide dust can show irritation symptoms of upper respiratory tract and deep mucosa of respiratory tract, such as sweet taste in mouth, forehead pain, dizziness, weakness, nausea and upper abdominal pain. Symptoms of chronic poisoning are decreased smell, headache and weight loss. The maximum allowable concentration of cadmium oxide dust is 0.1mg/m3, and the daily average concentration is 0.03 mg/m3. In case of poisoning, the poisoned person should be moved to a place with fresh air as soon as possible, quiet and warm. If there are symptoms of respiratory tract irritation, warm 2% sodium bicarbonate solution should be inhaled. Anti-toxic masks and protective glasses should be worn at work, seamless work clothes or jumpsuits should be worn, rubber gloves and aprons should be worn, and mouth should be gargle during and after work. |
| use | used as an intermediate in the manufacture of polyester, a flux for glass pigments, a catalyst for organic reactions, a plastic plasticizer, a stabilizer, and a raw material for the production of cadmium salts intermediates and insulating materials used in the manufacture of polyester. Used as a flux for glass pigments, a catalyst for organic reactions, a plasticizer and stabilizer for plastics, and as a raw material for the production of cadmium salts. Determination of sulfur. Rare earth optical glass manufacturing, electroplating and coloring. catalysts, plasticizers and stabilizers. Intermediate and insulating materials for making polyester can also be used as raw materials for producing cadmium salt. |
| production method | cadmium nitrate method cadmium ingot reacts with nitric acid to generate cadmium nitrate, then reacts with soda ash to generate cadmium carbonate, which is then washed, dried and crushed to obtain finished cadmium carbonate. Its 8HNO3 3Cd → 3Cd(NO3)2 2NO 4 H2OCd(NO3)2 Na2CO3 → CdCO3 2NANO3 hydrochloric acid method melts cadmium ingots, is poured into water to excite into granules, hydrochloric acid is added to dissolve to generate cadmium chloride, a small amount of nitric acid is added at the same time, ammonia water is added under stirring to adjust PH5 ~ 6, then a small amount of hydrogen peroxide is added to remove iron, after filtration, react with the prepared soda ash to Ph9 ~ 10, rinse with water to neutral, after filtration, it is dried at 120 ℃ to obtain cadmium carbonate finished product. Its Cd 2HCl → CdC12 H2 ↑ CdCl2 Na2CO3 → CdCO3 2NaCl |
