SPECTROPHOTOMETRIC DETERMINATION OF SULFATE IN PROPELLANTS AND NITROCELLULOSE

reportActive / Technical Report | Accession Number: AD0711884 | Open PDF

Abstract:

An accurate method is proposed for the determination of sulfate in propellants and nitrocellulose that requires only 45 minutes. The sample is treated with a mixture of nitric acid, perchloric acid and magnesium nitrate, and the solution is evaporated to dryness over a Bunsen burner. The salts are heated for 5 minutes with a mixture of hydriodic, hypophosphorous and hydrochloric acids in a simplified distillation apparatus while passing nitrogen through the system, the hydrogen sulfide which results from the reduction of sulfate is absorbed into ammonium hydroxide, lead citrate is added, and the brownish-yellow lead sulfide color is measured.
