- This compound darkens in air; impurities may be removed by treating a hot aqueous solution with sodium dithionite ( reducing agent ) and activated carbon, and allowing the product to cool crystallize.
- Working in a trailer, Ballard and Schwartz built a simple battery and Prater brought a sample of the lithium dithionite, and when they were placed together and charged, a weak current was produced.
- It should not be confused with sodium dithionite, Na 2 S 2 O 4, which is a very different compound, and is a powerful reducing agent with many uses in chemistry and biochemistry.
- Prater was able to quickly determine that no one knew what the product of the lithium-salt reactions in existing batteries were, and guessed that it was lithium dithionite, which he was able to synthesize.
- The car was carrying 148, 000 pounds of the chemical, sodium dithionite, a flammable product that can produce irritating, corrosive or toxic gases, said Patrick Conley, a spokesman for the Kentucky Division of Emergency Management.
- A completely distinct family of CCox is known as the cytochrome P450 oxidases, so named for the characteristic Soret peak formed by absorbance of light at wavelengths near 450 nm when the heme iron is reduced ( with sodium dithionite ) and complexed to carbon monoxide.
- Mechanical pulp is not a major cause for environmental concern since most of the organic material is retained in the pulp, and the chemicals used ( hydrogen peroxide and sodium dithionite ) produce benign byproducts ( water and sodium sulfate ( finally ), respectively ).
- An example of a modern totally chlorine-free ( TCF ) sequence is "'OZEPY "'where the pulp would be treated with oxygen, then ozone, washed with sodium hydroxide then treated in sequence with alkaline peroxide and sodium dithionite.

- Dithionite is often used in conjunction with complexing agent ( " e . g . ", citric acid ) to reduce iron ( III ) oxy-hydroxide into soluble iron ( II ) compounds and to remove amorphous iron ( III )-bearing mineral phases in soil analyses ( selective extraction ).
- A simplified three-step process for artificial divicine synthesis : ( 1 ) The benzyl group of 2-amino-5-benzyloxy-4-hydroxypyrimidine is removed by acid hydrolysis, yielding 2-amino-4, 5-dihydroxypyrimidine . ( 2 ) This intermediate is then treated with nitrous acid to yield the slightly soluble orange product, 2-amino-6-nitrosopyrimidine-4, 5-diol ( 3 ) which is then reduced with sodium dithionite to yield divicine.
