      on-line preconcentration of cadmium and copper.

AB  - A new functionalized resin has been applied in an on-line preconcentration system 
      for copper and cadmium determination. Amberlite XAD-2 was functionalized by 
      coupling it to 2-aminothiophenol (AT-XAD) by means of an NN spacer. This resin 
      was packed in a minicolumn and used as sorbent in the on-line system. Metal ions 
      were sorbed in the minicolumn, from which it could be eluted directly to the 
      nebulizer-burner system of the flame atomic absorption spectrometer (FAAS). 
      Elution of Cd(II) and Cu(II) from minicolumn can be made with 0.50moll(-1) HCl or 
      HNO(3). The enrichment factors obtained were 28 (Cd) and 14 (Cu), for 60s 
      preconcentration time, and 74 (Cd) and 35 (Cu), if used 180 s preconcentration 
      time. The proposed procedure allowed the determination of cadmium and copper with 
      detection limits of 0.14 and 0.54mugl(-1), respectively, when used 
      preconcentration periods of 180s. The effects of foreign ions on the adsorption 
      of these metal ions are reported. The validation of the procedure was carried out 
      by analysis of certified reference material. This procedure was applied to 
      cadmium and copper determination in natural, drink and tap water samples.
