AB  - A simple and sensitive method using microcolumn (20-mm length x 2.0-mm i.d.) 
      packed with black stone (Pierre noire) for the separation/preconcentration of Cd, 
      Co, Ni and Pb in biological samples prior to their online determination by 
      inductively coupled plasma optical emission spectrometry (ICP-OES) has been 
      developed. Optimal experimental conditions including pH, eluent concentration and 
      volume, sample volume and sample flow rate were investigated and established. The 
      adsorption capacity of black stone for Cd, Co, Ni and Pb were found to be 23.4, 
      21.2, 18.1 and 22.2 mg g(-1), respectively. With a preconcentration time of 72 s 
      and an elution time of 4s, an enrichment factor of 20 and a sampling frequency of 
      25 h(-1) were obtained. The detection limits corresponding to three times the 
      standard deviations of the blank for Cd, Co, Ni and Pb were found to be 0.3, 0.4, 
      0.4 and 1.1 ng mL(-1). The precision for seven replicate determinations of Cd, 
      Co, Ni and Pb gave relative standard deviations (RSDs) of 5.9, 4.8, 2.7 and 1.1%, 
      respectively (n=7, C=10 ng mL(-1)). The method was validated with certified 
      reference material GBW09103 human urine and the results obtained were in good 
      agreement with the certified values. The method was also applied to the 
      determination of the target analytes in biological samples with satisfactory 
      results.
