Determination of lead in propellant samples by atomic-absorption spectrophotometry

A procedure is described for the determination of lead in different types of propellant samples by atomic-absorption spectrophotometry. The method is simple, rapid and avoids the use of strong acids and prior sample digestion. Complete lead extraction is achieved with 10% acetic acid. The results obtained by the proposed method are compared with those obtained by the gravimetric chromate method. The variation of the efficiency of lead extraction with sample type is discussed.
