物理和化学特性
Sodium dithionite (also known as sodium hydrosulfite) is a white crystalline powder with a sulfurous odor. Although it is stable in dry air, it decomposes in hot 水 and in 酸 solutions.
应用n
a.sodium dithionite is used as a reducing agent in some industrial dyeing processes.
b.Sodium dithionite can also be used for water treatment, aquarium water conditioners, gas purification, cleaning, and stripping.
c.It has also been applied as a sulfonating agent.
d.In addition to the textile industry, this compound is used in industries concerned with leather, foods, polymers, photography, and many others, often as a decolourising agent.
e.It is the an active ingredient in “Iron Out Rust Stain Remover”, a commercial rust product.
f.Sodium dithionite is often used in physiology experiments. 此外, sodium dithionite is often used in soil chemistry experiments.Aqueous solutions of sodium dithionite were once used to produce ‘Fieser’s solution’ for the removal of oxygen from a gas stream.
g.It is used in Kodak fogging developer, FD-70.
安全
The wide use of sodium dithionite is attributable in part to its low toxicity LD50 在 2.5 g/kg (rats, oral).
