Summary

The inverse-voltammetric determination of the natural contents of lead and copper in beer is possible in a flow-through cell with medium exchange after UV-photolysis. The working conditions are given and the results are compared with those obtained by a wet oxidative digestion procedure. The relative standard deviations were: Cu 3.5% and Pb 1.4%.
