Scope

The sodium nitro-ferrocyanide is used as an indicator, the potassium
ferricyanide is used to oxidize impurities such as alkali metal sulfides in
xanthate into monomer sulfur to eliminate interferences. The chemical reaction
is.
Then the sodium rhodizonic acid is used as an indicator, and the lead acetate
standard solution is used to titrate the sodium xanthate. The chemical reaction
formula is.
