Abstract
A procedure is described for the determination of tin, lead, bismuth, copper, iron, silver, cadmium and zinc in Sn‐Pb alloy, composed of ca. 50% Sn, 47% Pb, and 3% Bi, by means of atomic absorption spectrophotometry. The sample is dissolved in aqua regia. Tin and lead are determined against standard solutions in which the Sn/Pb ratio is approximately the same as in the alloy. The relative precision, with respect to gravimetric determinations, is ca. 1.5%. For the bismuth, copper, iron, silver, cadmium and zinc determinations the standard addition method has been used.
