[Direct determination of Cu, Mn and Pb in wine and drink by GFAAS].
The determination of Cu, Mn and Pb in wine and drink by rapid GFAAS with automatic injection is described in this paper, which does not need ashing and digesting and without chemical matrix modifier. The graphite furnace's function of pre-treatment is fully used. The method is simple, rapid, accurate and practical. The result indicates that the relative standard deviation of Cu, Mn, Pb is 4.96%, 5.32% and 8.46% respectively, the recover rate is 95%-125%, 85%-106% and 88%-107% respectively.
