Nitricacid,cadmiumsalt - Preparation Method
Open Data Verified Data
metal cadmium method: the Electrolytic metal cadmium is added into an acid-resistant reactor containing ion-free water, and 30~6 ~ 35% dilute nitric acid is gradually added, and the reaction begins to be intense. When the reaction tends to be slow, gradually heated to 70~80 C, reaction 6~8H, so that the reaction solution is neutral, the solution is filtered, the filtrate is sent to the evaporator to concentrate until the surface of the solution to form a thin film. Then sent to the crystallizer for cooling crystallization, by centrifugal separation, dry in the air, prepared cadmium nitrate product. During the reaction, the oxidizing ammonia gas evolved, toxic, treatment method see sodium nitrate absorption method.

glass bottle packaging, each bottle of 0. 5kg net weight. The product shall be packed in wooden boxes for transport, and the package shall be marked with_drugs and "oxidant knife. It belongs to Class II inorganic oxidant, with risk code number; GB 5.1 class 51522, UN N0.1477; IMDG code 5.1, page 1. Should be stored in a cool, ventilated, dry warehouse. Stay away from heat sources and fire types. Not with organic matter, reducing agent, flammable materials co-storage and transportation. During transportation, it should be protected from rain, moisture and sun exposure. During loading and unloading, care should be taken to prevent package breakage. In case of fire, it can be suppressed by water, sand and all kinds of fire extinguishing. Toxicity and protection. Cadmium compounds are highly toxic. He presented with decreased sense of smell during chronic poisoning,. Cadmium rhinitis ", Head Pain, dizziness, loss of appetite, stomach pain, Nausea, Vomit, weight loss, urine protein. The victim will be moved to a fresh air location. Try to be quiet and warm. Respiratory irritation symptoms should be inhaled hot and humid 2% sodium bicarbonate solution, drinking hot milk containing soda or alkaline mineral water. The maximum allowable concentration of soluble cadmium salts is 0.2 mg/m3 in the United States. Production personnel should wear protective masks, rubber aprons, latex gloves and work clothes at work. Rinse your mouth during and after work. Production equipment should be closed and the working environment should be well ventilated. Production workers should have regular medical examinations.

| Use | for the manufacture of catalysts, batteries, cadmium-containing agents and other cadmium salts and cadmium oxides, analytical reagents, etc. used as reagents for the determination of zinc and ferrocyanide, but also for the preparation of other cadmium salts and catalysts calibration instruments and devices; Evaluation methods; Working standards; quality Assurance/Quality Control |
| production method | weigh 99% of metal cadmium, put it into a 1000mL beaker, first, wash with 1: 6 high-purity dilute nitric acid once, then rinse with electric conductive water, then slowly add 220 2:1 high-purity dilute nitric acid, and try to make some cadmium left (about 7g excess), after the end of the reaction, the solution is filtered with a sand core funnel, the clear filtrate is poured into a beaker, and when it is heated and concentrated to a certain concentration on an electric furnace, a glass rod is inserted into the evaporation liquid, when the rod was removed, the heating was stopped and the crystals were cooled if a wafer was found on the rod. The crystals were spin dried in a mini-centrifuge to obtain spectrally pure cadmium nitrate. The finished product was then placed in a desiccator containing P2O5 and dried at 60 °c under vacuum to give 170g of spectrally pure cadmium nitrate. |
