Toxicity
Cadmium chloride is a drug. Inhalation of cadmium chloride dust causes damage to respiratory organs and gastrointestinal tract. It is manifested as pain in the forehead, dizziness, weakness, nausea, and upper abdominal pain. The maximum allowable concentration is 0.2 mg/m3. Production workers should wear work clothes, anti-virus masks, rubber gloves and aprons and other labor protection supplies. The production equipment should be airtight, the workshop should be well ventilated, and the shower should be taken after work. Protect the respirator and skin.
production method
The sponge cadmium method heats and melts the sponge cadmium, pouring it into cold water to make cadmium flowers, and then reacts with hydrochloric acid to form a cadmium chloride solution. Potassium permanganate is added to remove iron and other impurities in the solution, and then clarified. Send the clear liquid to evaporate and concentrate, cool and crystallize, and centrifuge to obtain a finished cadmium chloride product. Its
