Abstract : Methods are proposed for the determination of soluble styphnate and nitrate in waste water from lead styphnate primer plants. The styphnate is extracted from the waste water with methylene chloride and is determined by measurement of the absorbance of the methylene chloride solution at 273 nm. The nitrate is determined in the aqueous solution left after the methylene extraction by measurement of the absorbance at 220 nm. PETN is extracted by the methylene chloride but does not interfere with the determination of the styphnate, since it shows no interfering peaks. Chloride, sulfate, phosphate, fluoride, and carbonate do not interfere with the determination of styphnate or nitrate. (Modified author abstract)
