No data available.

Section 13 - Disposal Considerations

APPROPRIATE METHOD OF DISPOSAL OF SUBSTANCE OR PREPARATION
Cautiously acidify a 3% solution or a suspension of the material
to pH 2 with sulfuric acid. Gradually add a 50% excess of aqueous
sodium bisulfite with stirring at room temperature. An increase in
temperature indicates that a reaction is taking place. If no
reaction is observed on the addition of about 10% of the sodium
bisulfite solution initiate it by cautiously adding more acid. If
manganese, chromium, or molybdenum are present adjust the pH of
the solution to 7 and treat with sulfide to precipitate for burial
as hazardous waste. Destroy excess sulfide, neutralize, and flush
the solution down the drain. Observe all federal, state, and local
environmental regulations.
