摘要: Digestion-free determination of trace-metals (Zn, Cd, Pb, Cu) in beverages by inverse voltammetry a flow-through cell equipped with mercury film-electrode is described. Optimal enrichment potentials are obtained inspection the pseudopolarograms elements original diluted sample solution. After deposition step untreated solution stripping effected proper supporting electrolyte after medium exchange. Values this techniques various samples compare well those usual procedures including wet digestion samples.
