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-pyridinoacetyt hydrazone) were retained on a column packed with Amberlite XAD-4 resin at pH 8-9. The metal complexes were removed from the co
