Paper Title:
Β-Cyclodextrin-Cross-Linked Polymer Microcolumn Dynamic Preconcentration/analysis for Trace Cadium
  Abstract

The adsorptive capability of β-Cyclodextrin-cross-linked polymer(β-CDCP) for cadmium was assessed in this work using column method. It was found that the complex (Cd(II)-5-Br-PADAP) could be quantitatively retained on the β-CDCP in the pH 8.5, eluted completely with 1.5 mol×L-1 HCl. Under the optimum conditions, the linear range, detection limit (DL) and the relative standard deviation (R.S.D.) was 2.0-60.0 μg×L-1, 7.8 ng×L-1 and 2.20% (n=3, c=20.0 μg×L-1) respectively. The separation of Cd(II) was achieved from water samples with an enhancement factor of 20. Moreover, the β-CDCP could be used repeatedly and offered better recovery. The method was validated using a certified reference material, and applied for the determination of trace cadmium in water samples.
