Abstract
The optimum conditions for the determination of Cd, Pb, and Cu in beer were sought by the factorial design and the simplex method approaches. Two methods of sample treatment were used, viz. mineralization and mineralization combined with ashing. The values obtained, 0.32 μg l-1 for Cd, 15.6 μg l-1 for Pb, and 64.7 μg l-1 for Cu, were compared with those obtained by atomic absorption spectrophotometry.Keywords
