Description

Technical Field

[0001] The utility model relates to the technical field of sodium periodate acidification, in particular to an automatic sodium periodate acidification device. Background Art

[0002] Sodium periodate is an important iodine-containing oxidant, a colorless or white crystalline powder, easily soluble in water, acetic acid and other solvents, but insoluble in ethanol. Its synthesis involves the oxidation of sodium iodate with sodium hypochlorite under alkaline conditions, acidification to obtain a solution, and then concentration and drying. The acidification process is exothermic and dangerous, and the use of nitric acid, a strong oxidizing and corrosive acid, is extremely dangerous to contact with its vapor. Nitric acid has a strong irritating and corrosive effect on the skin and mucous membranes. Inhalation can cause acute poisoning, and oral administration can cause corrosive stomatitis and gastroenteritis, and even shock or renal failure. In the prior art, the reaction temperature, endpoint test and nitric acid dripping control are all operated on site, which is risky and difficult to control accurately. Therefore, close-range operation should be avoided when using nitric acid, and a safer and more accurate control method should be sought. In view of this, in-depth research was conducted on the above-mentioned issues, and this case was created. Utility Model Content
