摘要：

The possibility of using the hanging mercury drop electrode in the direct determination of copper, lead, cadmium and zinc in wine samples is described here in a preliminary study.. Acidification of the sample allowed release metal ions and total metal contents is determinated. The interferences due the intermetallic compound Cu-Zn was investigated. Standard addition plots were linear in the experimental conditions used. The reliability of the method was tested by comparison with the results obtained with atomic absorption spectrometry. The differences were within 1-36% for copper. 1-27% for lead and 11-31% for zinc.
