Sequential Rapid Determination of Six Trace Elements in Grape Wine by Direct Sampling-High Resolution Continuum Source Graphite Furnace Atomic Absorption Spectrophotometry
An effective method had been developed for sequential rapid determination of six trace elements(Cd, Cu, Cr, Pb, Mn, Al) in grape wine by direct sampling-high resolution continuum source graphite furnace atomic absorption spectrophotometry. The interferences could be eliminated effectively by the selection of appropriate analytical spectral lines and matrix modifiers. Under the selected working conditions, the mass concentration of Cu, Cr, Pb, Mn, Al in grape wine were 138.8 ng/mL, 21.0 ng/mL, 2.11 ng/mL, 1....
