摘要：

An on-line sample pretreatment method was developed to preconcentrate trace metal ions from water samples. Complexes of metal ions with butane-2,3-dione bis(N-pyridinoacetyl hydrazone) were retained on a column packed with Amberlite XAD 4 resin at pH 8-9. The metal complexes were removed from the column with an acidic eluent and detected by inductively coupled plasma mass spectrometry. The metal ions studied were Cu, Cd, Co, Ni and Pb. The detection limits were in low ng l-1 range for the elements studied. The method was applied to the determination of various trace metals in the riverine reference material SLRS-2.
