摘要：
A method for determination of zinc, cadmium, lead and copper in wines by means of potentiometric stripping analysis (PSA) is described. Cadmium, lead and copper are determined directly, whereas the zinc determination is possible only after the wine samples decomposition. The results for five red and white Yugoslav wines are given. The contents of zinc, cadmium, lend and copper in analyzed samples were in the range of 0.16-0.79, 0.010-0.045, 0.13-0.27 and 0.10-0.46 mg/l, respectively. The contents of the all analyzed metals were below the maximum ordered by the Yugoslav law.
