AB  - A new method for separation/preconcentration of trace amounts of Cr, Cu and Pb in 
      environmental samples by magnetic solid-phase extraction (SPE) with 
      Bismuthiol-II-immobilized magnetic nanoparticles and their determination by 
      ICP-OES has been developed. The separation of the target analytes from the 
      aqueous solution containing the target analytes and Bismuthiol-II-immobilized 
      magnetic nanoparticles was simply achieved by applying external magnetic field. 
      Optimal experimental conditions including pH, sample volume, eluent concentration 
      and volume and co-existing ions have been studied and established. Under the 
      optimal experimental conditions, the detection limits for Cr, Cu and Pb with 
      enrichment factors of 96, 95 and 87 were found to be 0.043, 0.058 and 0.085 
      ngmL(-1) and their relative standard deviations (R.S.D.s) were 3.5%, 4.6% and 
      3.7% (n=5, C=2 ngmL(-1)), respectively. The method was validated with certified 
      reference material (GBW50009-88) of environmental water sample and the analytical 
      results coincided well with the certified values. Furthermore, the method was 
      successfully applied to the determination of target analytes in river and lake 
      water samples. Compared with established methods, the proposed method is 
      characterized with high enrichment factor, fast separation and low detection 
      limits.
