摘要：

A method is described for the determination of μg/g to mg/g concentrations of As in lead and lead alloys. For that purpose arsenic is blown out from the sample solutions as AsH3 by use of NaBH4 and determined by AAS in a heated quartz cuvette. Using suitable conditions disturbances caused by the matrix are eliminated. The relative standard deviation over the whole working range is about 3% (N=12); the detection limit (3 σ) was found to be 0.1 μg/g As. © 1979 Springer-Verlag.
