Fuming nitric acid is a toxic liquid containing 90% to 97.5% nitric acid. Highly corrosive, violently smokes in the air and absorbs moisture. Is a strong oxidizing agent, contact with strong reducing agents may explode, contact with organic matter there is a risk of fire.
【 Main purpose 】
Nitric acid is an important chemical raw material and an important reagent necessary in laboratories. In the industry can be used to make chemical fertilizers, pesticides, explosives, dyes, salts and so on
【 Packaging and Storage 】
The storage area should be isolated from other compartments, well ventilated, away from light and away from heat sources. Use acid-proof flooring. A large storage area should be walled or gated to prevent it from spreading outwards in case of leakage. And a neutralizer. Fire hydrants and oxygen gas masks should be provided outside the storage for first aid.
【 Quality index 】
Nitric acid, ω% ≥ 98%; Nitrous acid, ω% ≤ 0.5%
Sulfuric acid, ω% ≤ 0.08%; Burning residue, ω% ≤ 0.02%
Note: The control of sulfuric acid content is limited to concentrated nitric acid obtained by sulfuric acid concentration process
