In order to verify the applicability of the developed methodology, four alloys real samples as bronze, lead bronze, copper-base alloy 1, and bronze 1883 supplied by Centro de Pesquisa e Desenvolvimento do Estado da Bahia (CEPED) were analyzed and results are shown in Table 1. These samples were also analysed by FAAS or ICP-AES. As can be seen, all measured values agreed well with those measurements per-formed by FAAS or ICP-AES.
