I. The document proposes an accurate spectro photometric method for determining sulfate in propellants and nitrocellulose that requires treating samples with nitric and perchloric acids, reducing sulfate to hydrogen sulfide using a hydriodic-hypophosphorous-hydrochloric acid reagent, absorbing the hydrogen sulfide in ammonium hydroxide, and measuring the brownish-yellow lead sulfide color formed. II. It is recommended that the described method be added to military specifications for propellants to provide
