AB  - In the present work, a dispersive liquid-liquid microextraction based on the 
      solidification of floating organic drop (DLLME-SFO) combined with inductively 
      coupled plasma mass spectrometry (ICP-MS) was developed for the determination of 
      Pb, Co, Cu, Ni, Zn. The influences of analytical parameters, including pH, 
      extraction solvent volume, disperser solvent volume, concentration of chelating 
      agent on the quantitative recoveries of Pb, Co, Cu, Ni, Zn were investigated. The 
      effect of the interfering ions on the analytes recovery was also investigated. 
      Under the optimized conditions, the limits of detection were 0.97-2.18 ng L(-1). 
      The relative standard deviations (RSDs) were 2.62-4.51% (n=7, C=20 ng L(-1)). The 
      proposed method was successfully applied for the analysis of ultra trace metals 
      in wastewater samples.
