잠재적 노출
Arsenic pentoxide is used in production
of metal arsenates; as an herbicide, defoliant on cotton;
as a chemical intermediate; as an ingredient in wood preservatives;
and in glass. Other possible uses are as an insecticide
and soil sterilant.
Decomposes above 315 C, forming oxygen
and arsenic trioxide fumes. Arsenic pentoxide is an
oxidizer; reacts violently with bromine pentafluoride and
reducing agents. The solution in water is a weak acid.
Incompatible with acids, strong alkalis; halogens, rubidium
carbide, zinc. Corrosive to metals in the presence of moisture.
Contact with acids or acid mists releases deadly arsine
gas.
폐기물 처리
Dissolve in a minimum of
concentrated hydrochloric acid. Dilute with water until
white precipitate forms. Add HCl to dissolve. Saturate with
H2S; filter and wash precipitate and return to supplier.
Alternatively, precipitate with heavy metals, such as lime
or ferric hydroxide in lieu of H2S. If needed, seek
professional environmental engineering assistance from
the United States Environmental Protection Agency
Environmental Response Team at (908) 548-8730 (24-hour
response line). Consult with environmental regulatory agencies
for guidance on acceptable disposal practices.
Generators of waste containing this contaminant (≥100 kg/
mo) must conform with EPA regulations governing storage,
transportation, treatment, and waste disposal. In accordance
with 40CFR165, follow recommendations for the disposal
of pesticides and pesticide containers. Must be disposed
properly by following package label directions or by contacting your local or federal environmental control
agency, or by contacting your regional EPA office.
