Dissolution is slightly soluble in water, in addition to the concentrated sulfuric acid, and other acid.
Preparation or source of metal antimony and antimony trioxide and nitric acid.
In the 380 ℃ lose oxygen and other four antimony oxide.In the 930 ℃ from loss of oxygen antimony trioxide.Soluble in alkali into antimonate.
Danger tag 15 (harmful product, away from the food) main application used in the manufacture of antimonate, antimony compounds and pharmaceutical industry
2. The impact on the environment:
A health hazard
Invasive ways: inhalation, eat
Health hazard: antimony can irritate the mucous membrane, can cause damage to the internal organs.
Acute poisoning: contact with relatively high concentrations of cause chemical conjunctivitis, rhinitis, pharyngitis, laryngitis, bronchitis, pneumonia.Oral cause acute gastroenteritis.Systemic symptom can have fatigue, dizziness, headache, limb muscle soreness.Can cause heart, liver and kidney damage.
Chronic effects: there is often a headache, dizziness, excitable, insomnia, fatigue, gastrointestinal dysfunction, mucous membrane irritation.Can cause nasal septum perforation;In the process of antimony smelting antimony can cause pneumoconiosis.

Dangerous characteristic: weak oxidant.And reducing agent can react.
Combustion products (decomposition) : antimony oxide.
3. The emergency monitoring methods:
4. Laboratory monitoring methods:
Antimony in different valence state analysis method of antimony oxide [issue] / yan the us and the UK;Theresa foo / / metallurgy analysis. - 1988, 8 (5) - 31 ~ 34 abstract in analytical chemistry > 1989.6.
5. Environmental standards:
The former Soviet union maximum allowable concentrations of harmful substances in the air of workplace 2 mg/m3 (Sb)
6. The emergency disposal method:
A, leakage emergency handling
Isolation leakage pollution area, restricted movement.Recommended emergency personnel to wear self-contained breathing apparatus, in general work overalls.Don't direct contact with the leakage.A small leak: avoid dust, use clean shovel collection in a dry, clean, covered container.A large number of leak: covered with plastic cloth, canvas, reduce flying.Then collect the recycling or shipped to the disposal of waste places.
Second, the protective measures
Respiratory protection: when may contact the dust, workers should wear dust respirator filter type.When necessary, wear air breathing apparatus, oxygen mask respirator or a long tube.
Eye protection: wear chemical safety goggles.
Body protection: penetration type gas protective clothing.
Hand protection: wear chemical glove.
Other: work site no smoking, eating and drinking water.Work, shower change clothes.Kept by poison pollution clothes, wash the backup.To maintain good health habits.
Three, first aid measures
Skin contact: remove contaminated clothing and water with soap and water to thoroughly flushed the skin.
Eye contact: mention eyelid, irrigate with flowing water or normal saline, go to a doctor.
Inhalation: quickly from the scene to fresh air.Keep respiratory tract unobstructed.Such as difficulty in breathing, give oxygen.If breathing stops, artificial respiration immediately.Go to a doctor.
Eating: drink enough water, vomiting, gastric lavage.Go to a doctor.
Fire extinguishing methods: agent: water, sand.
